Ken Hutchins' analysis is not just book theory; it is based on real experience training many, many thousands of subjects over a span of decades. He trained everyone from amateur and professional level athletes and bodybuilders to little old ladies with osteoporosis and also a great many genetically normal/average folks. He assisted Arthur Jones and Ellington Darden at Nautilus Sports Medical Industries where he first refined the Superslow method during a 5 years long clinical trial, the Nautilus Osteoporosis Study at The University of Florida Medical School in Gainesville (the study is mentioned in chapter 8 of the 1990 edition of "The Nautilus Book" by Ellington Darden, a book I highly recommend for beginning HIT practitioners). Hutchins' writing is as dry and clinical as one would expect to find in any textbook about medicine or engineering. It is also filled with rich insight into the intellectual processes and long history of carefully controlled experiments at Nautilus (and later Hutchins' own facilities) that brought Ken Hutchins to his current level of knowledge. His understanding of anatomy, biology, physics, engineering, psychology, history and sociology are all put to good use in this book and should enthrall any reader that possesses solid critical-thinking skills. Understanding the arguments for a distinction of "Exercise vs. Recreation", "The First Definition of Exercise" and "Requirements for Functional Ability" are crucial for everyone that cares even the slightest about the subject of human health, fitness, longevity or quality of life. These are not trivial matters.
After trying many different workout "schemes" with limited success, I bought this book and began doing Super Slow workouts. I'm now working out 6 times a month, spending less than 30 minutes in the gym for each workout, and I'm stronger than I've ever been. I've never experienced progress like this before. At 45 years old, my leg press has gone from 400 to 820 lbs. in a couple of months. The workouts aren't easy, but they're over quickly, and I'm able to spend more time with my family without feeling like I'm compromisng my health and fitness.

The MCT group was prescribed two weekly exercise sessions of 50-min continuous activity at 70% of peak heart rate, or approximately 13 on the Borg 6–20 rating of perceived exertion (RPE) scale [20]. The HIIT group was prescribed two exercise sessions a week with 10-min warm-up followed by 4 × 4 min intervals at 85–95% of peak heart rate, or approximately 16 on the Borg 6–20 RPE scale. The participants were given individual oral and written information about the training methods, including information about frequency, duration, intensity and examples of exercise sessions. The participants were free to exercise individually, with an exercise type and at a location of their own choosing. Every sixth week the participants met for a supervised spinning session where they exercised with a heart rate monitor. These exercise sessions gave the participants an opportunity to control their intensity during exercise. In addition, organized group exercise was offered twice per week for motivational purposes. Attendance to these exercises was voluntary and the activity performed varied between indoor and outdoor activities such as walking, jogging and aerobics [19]. Besides the two prescribed exercise sessions, the participants were free to exercise as desired.

Collectively, these findings demonstrate that exercise may serve as a substitute or competition for drug abuse by changing ΔFosB or cFos immunoreactivity in the reward system to protect against later or previous drug use. ... As briefly reviewed above, a large number of human and rodent studies clearly show that there are sex differences in drug addiction and exercise. The sex differences are also found in the effectiveness of exercise on drug addiction prevention and treatment, as well as underlying neurobiological mechanisms. The postulate that exercise serves as an ideal intervention for drug addiction has been widely recognized and used in human and animal rehabilitation. ... In particular, more studies on the neurobiological mechanism of exercise and its roles in preventing and treating drug addiction are needed.
Stability moves train your core to stay strong and steady. They also target your transverse abdominis, the deep ab muscle that does a 360 around your waist and draws it in, says Brent Brookbush, president of the Brookbush Institute of Human Movement Science in New York City. Try this stabilizer: Hold a dumbbell in your right hand and balance on your left leg. Squat on your left leg as you lower the weight toward your left foot. (More moves to try: grab a Bosu ball and challenge your core with this stability workout. Or you can snag one of these balance boards to work on your core as you watch your favorite TV show.)
Given that "Superslow" is long out-of-print and much more research and refinement has occurred since the early 1990's I am hesitant to recommend it to anyone other than hardcore collectors of bodybuilding or exercise related ephemera. Ken Hutchins recently updated the entire Superslow manual and further elaborated on many more topics by publishing "The Renaissance of Exercise: A Vitruvian Adventure Volume I" (2011) which is only available via mail-order and not in retail stores. It doesn't even have an ISBN number inside. But "The Renaissance of Exercise" will give you the majority of chapters from the original SuperSlow technical manual in a much more durable hardcover textbook format. It is 320 pages of no-holds-barred Ken Hutchins simply telling the truth about what he has learned after 35 years spent rigorously studying exercise. Considering current prices of some used copies of "Superslow" for sale here on Amazon you might as well spend the $150 with the folks at RenEx and you'll get _WAY_ more for your money. You can also read some of those chapters/articles for free on the RenEx website or at Hutchins' website called SuperSlow Research Zone.
The recent “consensus statement” of the European College of Sport Science indicates that the difference between NFO and OTS is the amount of time needed for performance restoration and not the type or duration of training stress or degree of impairment.1 In essence, it is generally thought that symptoms of OTS, such as fatigue, performance decline and mood disturbances, are more severe than those of NFO. However, there is no scientific evidence to either confirm or refute this suggestion.1 The distinction between NFO and OTS is most of the time based on “time to recover”. Hence, there is a need for objective, immediately available evidence that the athlete is indeed experiencing OTS.
Natural movement-harmonizing exercises and stretches have likely been practiced since the beginning of mankind. Forms of non-strenuous rhythmical functional movements were used for three main purposes: To manage and prevent musculoskeletal disorders, to maintain a naturally healthy body and mind, and to enhance athletic performance. Around the turn of the 20th century, at least six independent Western modern mind–body (MMB) methods emerged simultaneously. This phenomenon occurred during the same era in which Einstein, Picasso, Freud, and Stravinsky also broke away from dominating and restrictive establishment controls, subsequently freeing their fields. The cultural changes and personal emancipation that MMB pioneers brought to the exercise world were no less dramatic, yet significantly less documented.
Yoga also offers many mental benefits, such as a reduction in stress level. Greater relaxation and reduced stress leads to a host of other positive body changes including an improvement in circulation, sleep and self-confidence. A positive mental outlook also helps to maintain a healthy immune system, which in turn can ward off other serious ailments such as high cholesterol, heart disease and stroke.
In the present study, we measured muscle endurance by completion of time to exhaustion tests where the subject has to maintain a fix workload for as long as possible. All time to exhaustion tests lasted less than ten minutes, confirming that OLDE was performed at high intensity. The duration of the time to exhaustion tests in the present study is in accordance with previous studies using the same exercise on a different ergometer [11, 17, 18]. Relative reliability refers to the degree to which individuals maintain their position in a sample with repeated measurements [30]. The ICC value of 0.795 can be interpreted as a questionable reliability (ICC < 0.8), close to the threshold for good reliability (0.8 < ICC < 0.9) [19]. However, as no consensus really exists on threshold to interpret ICC results [31], the practical significance of its value has to be determined with caution by the readers according to their future use of the present protocol. Absolute reliability refers to the degree to which repeated measurements vary for individuals [30]. Traditionally, time to exhaustion tests are known to present a greater CV (CV > 10%) than time trials (i.e. subjects has to perform the greater amount of work possible in a fixed time/distance; CV < 5%) [20]. Interestingly, in our study the CV is below 10%, confirming the great reliability of our novel high intensity OLDE protocol to measure muscle endurance, this despite the small sample size, chosen to be in accordance with previously published studies using the same protocol [8, 11, 17]. This great reliability is confirmed by the typical error of measurement value of 0.30 min, corresponding to 5% of the averaged performance value. Finally, as the typical error of measurement value was slightly above the smallest worthwhile change calculated (0.28 min), it is unlikely that our novel high intensity OLDE protocol can be used to detect small differences in performance.
Training to Failure. During most lifts with a moderately heavy weight, the set is completed before failure is reached. Muscles feels taxed, the sweating has begun, a few more sets are rocked, and we move on to the next exercise. This is a great way to get stronger, but is taking a set to failure an even better way? Yes and no Muscle Activation strategies during strength training with heavy loading vs. repetitions to failure. Sundstrup, E., et al. 1 National Research Center for the Working Environment, Copenhagen, Denmark 2, Institute of Sport Science and Clinical Biomechanics, University of Southern Denmark, Odense, Denmark 3Department of Occupational and Environmental Medicine, Bispebjerg University Hospital, Copenhagen, Denmark. Journal of Strength and Conditioning Research. 2012 Jul;26(7):1897-903.. While training to failure — lifting until the body can't do a single more rep — recruits more muscle and triggers the body to release more strength-building hormones, it’s most effective if a very high percentage of a one rep max can be performed The application of training to failure in periodized multiple-set resistance exercise programs. Willardson, J.M.

Also, sets to failure increase the opportunity for overtraining and injury, so it’s best to use this technique only occasionally and with a spotter.
The military press is similar to the shoulder press but is performed while standing with the feet together. (It is named "military" because of the similarity in appearance to the "at attention" position used in most militaries) Unlike the seated shoulder press, the military press involves the majority of the muscles of the core as stabilizers to keep the body rigid and upright, and is thus a more effective compound exercise.
The EMG signals were filtered with a Butterworth band pass filter (cutoff frequencies 20 and 400 Hz). Then, the root mean square (RMS) of the EMG signal was automatically calculated with the software. During the incremental test, the EMG RMS was averaged for the last 5 EMG bursts of each step (at the end of each minute) and at exhaustion. During the time to exhaustion tests, the EMG RMS was averaged for the last 5 EMG bursts prior each time point measurement (10, 20, 30, 40, 50, 60, 70, 80, 90 and 100% of the time to exhaustion). EMG RMS of each muscle during the time to exhaustion tests was normalized by the maximal EMG RMS of the respective muscle obtained during the pre-exercise KE MVC performed at 100 deg/s. During the KE MVCs, maximal EMG RMS was averaged over a range of 20 deg extension (± 10 deg) around the peak torque.
A compound exercise is a move that incorporates multiple muscle groups, like lunges, deadlifts, and squats. It may also refer to two moves being strung together, like a bicep curl to a shoulder press. Compound exercises are efficient for increasing overall muscle mass and burning calories (because they require more effort to complete), as opposed to isolation exercises, which focus on working just one muscle group (like a bicep curl).
Back in mid-century America, you did old-style sit-ups, which were once regarded as the gold standard of iron-gut, military discipline. Maybe they still are, so if your idea of "manly" is messing up your lower back, go for it. But few fitness trainers recommend old-style sit-ups, though there are some re-conceptualized versions of them that might work for you.
16.  Make sure you stay hydrated! Even mild dehydration hampers recovery. The drink of choice? Water! And for mineral replacement, especially sodium, I make sure my diet includes various amounts of celery, romaine lettuce, and a nutritional adjunct to the diet, a powdered barley grass juice called Daily Green Boost (if the foods I eat are grown in soils that are sodium insufficient, I won't get enough sodium, and if those foods that are supposed to be good sources of sodium don't taste savory, they are grown in sub-par soils).

You’re also extremely adaptable, so it’s a great time to explore, play, and learn new physical skills. “Younger people can handle new elements in their workouts every few weeks,” says Anderson, who trains teen athletes as well as octogenarians. Strong bones and muscles, fewer injuries, quick recovery, and naturally high levels of anabolic hormones allow you to make faster progress than at any other point in your life.

Frequency, intensity, type, location and social setting (alone vs. together with others) of exercise were assessed using exercise logs from 618 older adults (aged 70–77 years) randomized to MCT or HIIT. All participants completed exercise logs after each exercise session they performed during one year. Pearson Chi-square tests were run to assess the association between intensity, type, location and social setting of exercise with training group.
Strength (or “weight”) training exercises build muscle. One’s body naturally grows muscle until the age of 25. As we age, our body progressively loses muscle— unless you make an effort to maintain or build it. Strength is good for everyone, regardless of gender or age and helps in everyday activities. Muscle mass can significantly decrease your chances of obesity, diabetes, cancer, and osteoporosis. Gender does not affect one’s ability to grow muscle, but men can develop more muscle mass than women because men naturally have a higher percentage of lean muscle. Women, you will not turn into the Incredible Hulk by strength training — I say this because many women don’t do strength training out of a fear of getting “big.” I wish it were that easy!
The Instructor – This is one of the most important factors of your exercise video. If you don’t like the instructor, it will eventually irritate you enough to stop using it. Look for instructors that motivate you to work harder and push harder not work to end the video so you don’t have to listen to them anymore. It’s a plus for the instructor to actually have a fitness background of some kind, which is both for your safety and to give you the knowledge that the video has legitimate foundations in real fitness rather than just being something they did on a whim or for celebrity endorsement.
Indian yoga gurus started arriving to the West at the turn of the 20th century, however, yoga as it is known today only evolved as a popular method to ‘stay healthy and relaxed’ during the second half of the century.50 Syman S. The subtle body: the story of yoga in America. New York (NY): Farrar, Straus & Giroux; 2010. [Google Scholar] There was no contact found between the sporadic early yoga arrivals to the West and the MMB pioneers discussed within this research. However, Eastern mind–body practices profoundly influenced Randell and Morris, most probably via Vaughan, who had just returned from years of obstetric work and eye-opening behavioral observations in India prior to the inception of the St Thomas project in 1912.
In total, 1567 participants (790 women) met the inclusion criteria, fulfilled baseline testing and were randomized 1:1 into an exercise training group or to a control group. The exercise training group was further randomized 1:1 to either MCT or HIIT. Participants in the exercise groups were instructed to fill in exercise logs after each exercise session they performed. Data in the present study is based on the exercise logs from the first year of the intervention. Therefore, only participants in the exercise groups were included in the present study (n = 787). Dropouts in the exercise groups during the first year (n = 123) and those with no exercise logs (n = 46) were excluded. A total of 618 participants (291 women) were included in the analyses (Fig. 1). The study was approved by the Regional Committee for Medical Research Ethics (REK sør-øst B: 2015/945) and all participants gave their written informed consent before participation.
Along with prenatal vitamins and regular doctor’s appointment,The Bloom Method should be an essential part of your prenatal experience. Brooke’s knowledge and passion for pre-and-postnatal health and wellness is unmatched. Thanks to the regular workouts and the prenatal exercises that Brooke taught me, I feel amazing, and my belly is tight (no one can believe that I’m almost 7 months along!) The Bloom Method is a fundamental investment in baby and mommy’s health.
Rest-Pause Sets. The body is an amazing machine, with the right amount of rest it can surprise us with its tenacity. With a weight near your 3 or 5 rep maximum, perform as many reps as possible, then re-rack. Rest for 10 to 15 seconds, then grab it again and go at it. Make sure to keep correct form, and go/rest until you can't budge the bar. Make sure to only do this once.
10.  Work the whole body during one session. Exercising different muscle groups on different days is counterproductive. Your whole workout should take no longer than 45 minutes, and this includes time spent on a treadmill to move lymph fluid to prevent lactic acid pooling in muscles. (Forty-five minutes, once a week for a high level of fitness... who can't find time for that!)
