On a fixed income, Insanity has been something of a problem to obtain... that is, presuming that they don't have the program on YouTube, or something, already.
Something that has been working thus far is a combination of various exercise programs, and Atkins. Last year, around this time, weighing in at 293, and seeing that exercise alone wasn't helping, the doctor suggested Atkins. While the past few months have included some deviations from the typical diet, combining this diet with exercise has dropped the weight from 293 to approximately 230, with a height of 6'. The current exercise program comes from Bruce Lee's "Tao of Jeet Kune Do"; due to time restraints, it's been modified to focus on a specific series of exercises every day; the Monday-Wednesday-Friday exercises have been restricted to Monday and Friday, the Tuesday-Thursday-Saturday exercises have been relegated to Tuesday and Thursday, and running has been resigned to Wednesday and Saturday. The current plan involves doing one extra rep of each exercise, per the number of days; for example, since it's been 31 days since starting this particular series of exercises, 31 reps were done. In regard to running, a schedule of 60 seconds of running to 120 seconds of walking has been implemented, adding a minute of activity for each day since the beginning of this particular program; tomorrow, being the 32nd day of this program, will involve 11 minutes of running, in total, and 21 minutes of walking. Most of the available information on cardio - specifically, running, - has indicated that ten-second sprints, followed by 20 seconds of walking, is healthier, in general, for the body, than sustained jogging; as the goal is to improve on endurance and stamina foremost, the ratio of 1/2, walking/running, has been maintained, but the running is slower than a full sprint - still faster than a mere jog, - and the walking is maintained at a normal pace. This series allows for approximately 2.5 times faster running than walking.
Earlier programs included the "six-pack shortcuts" exercises suggested on Mike Cheng's YouTube channel; AKBAN wiki's suggested workout program; and, Jack LaLanne's workouts, per old episodes of his television program, and a random series of isometrics. Jack LaLanne always seems to suggest switching up exercises every so often, and without access to a gym or money to afford a workout program, these are the best exercises available, thus far. An elastic band is used in some of the exercises that call for weight-lifting, providing tension that simulates additional weight.
