Alicia Marie, celebrity trainer, says you can change your core with plank twist corkscrews. “Hold in low plank position, keeping your core muscles tight and your forearms flat,” she says. “Slowly rotate your hips to one side, being sure not to drop them to the floor, then rotate your hips back to center. With your core muscles still engaged, rotate to the opposite side. Alternate back and forth slowly, completing five reps on each side for a total of four sets.”
Vinylcise has been historically neglected, and probably for good reason: it's terrible, and not very effective—at least not since we've had visual media alternatives. Can you imagine trying to follow along to an audio-only workout? At any rate, these workout records first appeared in the early 1920s, and were usually accompanied by a paper foldout with exercise diagrams (see the image). The earliest of these records appear to be the set of five Wallace Reducing Records released in 1920-1922 by the Wallace Institute of Chicago and pressed by Columbia Records. These records were marketed towards women, aiming to help them "get thin to music." Other exercise records of the 1920s included Victor Records for Health Exercises, released in 1922, the Battle Creek Sanitarium Health Ladder, directed by John Harvey Kellogg and released by Columbia Records in 1923, and Walter Camp's Daily Dozen, released in 1924.
Jumping and throwing moves, punches, kicks, and swinging a club or a racket all require power, which comes from your core—and, yes, causes those ab muscles to cinch. "The core is the crossroads of your system, helping transfer force between your upper and lower body," says Rick Richey, a faculty member for the National Academy of Sports Medicine in New York City. Add medicine ball throws to your sets: A study in the Journal of Strength & Conditioning Research found they are ideal core strengtheners. (Don't just stop at tossing, medicine balls can be used for a full body workout.)

Most studios offer yoga mats for your use, but you should purchase a fitness mat if working out at home. You’ll also need comfortable clothing, as you will flex your body into a variety of positions. You will most likely be barefoot, so purchasing specific footwear is not usually necessary. Other items such as straps and balls can accompany yoga routines, but they may not be necessary right away or even at all. A water bottle and towel will help you to stay hydrated and comfortable during your class. You will be bending and stretching, so it’s best to avoid heavy meals a few hours before your class.
The beneficial effect of exercise on the cardiovascular system is well documented. There is a direct correlation between physical inactivity and cardiovascular mortality, and physical inactivity is an independent risk factor for the development of coronary artery disease. Low levels of physical exercise increase the risk of cardiovascular diseases mortality.[22]

In summary, if you're only interested in a basic understanding of HIT methodology and where much of it originated I would suggest starting with a far less technical book. I suggest starting with the last published edition of Ellington Darden's "The Nautilus Book" and perhaps "Total Fitness: The Nautilus Way". If you like what you read and want to dig a little deeper into the evolution of HIT read Darden's more recent book, "The New High Intensity Training: The Best Muscle-Building System You've Never Tried". If the gears in your head are in high gear after that and you really want to get DEEP into what evolved from the original Nautilus protocol _then_ you go for "Superslow" or preferably "The Renaissance of Exercise: A Vitruvian Adventure Volume 1". When your grasp of all the aforementioned material is truly solid then move on to Doug McGuff's writing. McGuff's ideas do not surpass or supplant Hutchins' but rather sharpen the points with brilliant thoughts and clinical observations from a medical physician's perspective. Doug McGuff, MD published his "Ultimate Exercise: Bulletin #1" in the late 90's and later updated that with "Body by Science: A Research Based Program to Get the Results You Want in 12 Minutes a Week", both of which are hugely valuable contributions to the literature on HIT methodology and philosophy. His article about "Stoicism in Training" is critical reading.

Budget IS Important, But… – It’s always a good idea to have a budget in mind when it comes to buying anything, but don’t look for the cheapest exercise videos on the market. The adage you get what you pay for is definitely true. That doesn’t mean to spend way over your budget either. The point of this particular tip is that you should look for good quality videos and keep your budget in mind as well. Not all inexpensive videos are bad of course, but buying simply from a price point can quickly add up to nothing but a collection of dusty, unused exercise videos on your shelf.
Several exercises from Week 1 are carried over to Week 2, but one move is added to each bodypart routine—with the exception of abs—so you can train all muscle groups more completely from multiple angles. Chest, for example, includes two exercises: One is a compound movement (dumbbell bench press) that involves multiple joints (both the shoulder and elbow) to work the largest amount of muscle possible, and the other is an isolation exercise (dumbbell flye) that involves only one joint (shoulder) and targets the pecs to a greater extent. (When doing presses for chest, the deltoids and triceps are involved to a degree, meaning presses don’t isolate the pecs as much as flyes do.)

A Polar ( heart rate monitor (belt and watch) is used to measure heart rate continuously. A transmitter belt is fastened around the chest while the watch is held by a nearby observer. If at any time during the experiment the heart rate exceeds the predetermined ceiling (85% of age-predicted max heart rate) the experiment should be stopped immediately.
Brovold et al. [7] supposed the importance of an exercise is based on a high-intensity and continuous monitoring model because in their research a nonmonitored home-based group did not improve their physical fitness as much as the monitored group that accomplished a high-intensity aerobic exercise adjusted by means of the Borg Scale and a musical pace [25]. However, Brovold et al. [7], despite an exercise protocol with a high-intensity aerobic interval (HIA), found a small effect on SFT. This may be due to the fact that the exercise protocol used by Brovold et al. [7] did not interact favorably with the skills tested by SFT. Thus, a positive relationship among vigorous physical exercise [17] or HIA exercise [7] and the functional abilities tested by the SFT is not fully evident. On the contrary, the vigorous exercise protocol used here enhanced 5 out of 6 of the SFT and seems to be more focused than the aforementioned one. The small effect of vigorous physical exercise through the 8-foot up and go test is not fully clear and may depend on several factors: (i) a large standard deviation at T0 due to the presence of two subjects who showed a very low functional capacity; (ii) inadequacy of the exercises to improve this ability; and/or (iii) inadequate sensitivity of an 8-foot up and go test. In a recent study by Furtado et al. [15] conducted on a large number of elderly females, even though the SFT was used at baseline and after 8 months from an intervention program of multimodal exercise training (3 days per week), not all skills tested were found improved. However, according to a meta-analysis [11] that included 18 different exercise studies, even a small positive effect can be considered to be of great value in this group of individuals who are at risk of further functional decline. In conclusion, the present study shows that vigorous physical exercise in healthy elderly people provides significant improvements in the majority of the different skills assessed by the SFT.
