Do you want low, medium or high impact workouts? – Impact is important when it comes to how intense you workout is. Do you need or want low impact or do you want to really take it up a notch (or several) and get a challenging workout that will have you begging for it to be over? Most exercise videos will give you information on what kind of impact you will experience by doing it.

I believe we are coming around to the conclusion that what was recommended for years by the medical community (30 minutes of "aerobic exercise" 3-5 times a week, getting the heart rate up to 80% max. for age, etc.) has been inadequate, and of too low an intensity level. When an activity is of sufficient intensity, and not of a certain duration or repeated a certain number of times, the body will initiate a total-body response (metabolic, HDL, glucose tolerance, blood pressure, bone mineral density, immune competency, etc.) It appears that if this level of intensity is never reached, regardless of the amount of time spent or the frequency it is repeated, the beneficial response by the body never occurs, or is at least blunted.

J Psychiatr Res. 60C: 56–64. doi:10.1016/j.jpsychires.2014.10.003. PMC 4314337. PMID 25455510. Consistent evidence indicates that exercise improves cognition and mood, with preliminary evidence suggesting that brain-derived neurotrophic factor (BDNF) may mediate these effects. The aim of the current meta-analysis was to provide an estimate of the strength of the association between exercise and increased BDNF levels in humans across multiple exercise paradigms. We conducted a meta-analysis of 29 studies (N = 1111 participants) examining the effect of exercise on BDNF levels in three exercise paradigms: (1) a single session of exercise, (2) a session of exercise following a program of regular exercise, and (3) resting BDNF levels following a program of regular exercise. Moderators of this effect were also examined. Results demonstrated a moderate effect size for increases in BDNF following a single session of exercise (Hedges' g = 0.46, p < 0.001). Further, regular exercise intensified the effect of a session of exercise on BDNF levels (Hedges' g = 0.59, p = 0.02). Finally, results indicated a small effect of regular exercise on resting BDNF levels (Hedges' g = 0.27, p = 0.005). ... Effect size analysis supports the role of exercise as a strategy for enhancing BDNF activity in humans.
The deadlift is performed by squatting down and lifting a weight off the floor with the hand until standing up straight again. Grips can be face down or opposing with one hand down and one hand up, to prevent dropping. Face up should not be used because this puts excess stress on the inner arms. This is a compound exercise that also involves the glutes, lower back, lats, trapezius (neck) and, to a lesser extent, the hamstringcacas and the calves. Lifting belts are often used to help support the lower back. The deadlift has two common variants, the Romanian deadlift and the straight-leg-deadlift. Each target the lower back, glutes and the hamstrings differently.
For active types, nagging injuries nag a little louder; hard workouts deplete you a bit more. For serious recreational athletes, performance begins to drop, even if you maintain your training regimen. Whatever your sport of choice — be it distance running, competitive cycling, or pick-up basketball — you can expect your performance to plateau and recovery to take a bit longer.

Alternatively, anaerobic means an “absence of free oxygen.” It’s any form of high-intensity exercise that leaves you winded relatively quickly. A well developed aerobic system can produce energy for a long time, while your anaerobic capabilities cease anywhere from 10–120 seconds. Weightlifting, sprinting, plyometrics and HIIT are examples of anaerobic exercise. Explosiveness and an ability to generate power and or speed in small bursts is a trait of athletes that require anaerobic capabilities. Interestingly, the more developed your aerobic system, the longer it takes to burn through your anaerobic system. In this respect, you can think of aerobic exercise as a building block for anaerobic capacity.
17.  If you're getting a normal amount of usable protein (about one gram per five pounds of body weight), your body will require a bit more protein than usual as you increase lean muscle tissue). Uncooked protein is preferable to cooked protein (cooking denatures proteins, damaging them, and making them appear as a foreign invader to the body which can trigger an autoimmune response). A good source of protein is fruits, vegetables, and nuts. (Yes, nuts have fat too, but it's "good" fat, and your body needs fat in your diet; you can have a lean body while eating the right kinds of fat!) Give your body the additional protein as it asks for it. Listen carefully, and you'll know when. Remember, it's very difficult to get too little protein; most people get way too much, and too much protein is a cause of degenerative disease. (See Fact or Fiction: High protein diets are great for losing weight)
Who says you have to jump, grunt, strain and punish your body to get amazing results from your workout? Not with PiYo. PiYo combines the muscle-sculpting, core-firming benefits of Pilates with the strength and flexibility advantages of yoga. And, we crank up the speed to deliver a true fat-burning, low impact workout that leaves your body looking long, lean and incredibly defined.
The novelty of the present study is that of demonstrating the possibility of applying a specific vigorous physical exercise program [17] on healthy elderly adults over 65 years and evaluating its effects on functional capacity using the classical SFT [3]. To administer the high exercise intensity, we used a HR control under continuous accurate visual monitoring by a sport scientist. As expected, after only 12 weeks of training, we found significant enhancements of almost all skills tested. Our results clearly show that our VE program is relevant and has a positive impact on people over 65 in helping them to maintain a high quality of life. The difference from most of the literature [18–22] regards the exercise protocol intensity, which is usually milder than ours. Also, in the aforementioned studies there was a poor attention about the consequences of the exercise program on general quality of life of subjects. They mainly focused on the attenuated risks of falling. On the contrary, the SFTs applied in our study clearly show that our VE program may ameliorate several motor abilities and in turn the general quality of life in healthy elderly adults over 65 years of age. However, two other studies showed that elderly people need to exercise close to their limit of maximum capacity [23, 24] to improve their physical fitness but, unlike the present research, they were conducted on patients who were in deconditioning status linked to their chronic illnesses.
