My background is in Physical Therapy.
Many know that workouts come and go in the fitness fad. The Jane Fonda workout routines are in my opinion the very best for the beginer to intermediate level of training. I recomend this routine as pretraining to all other activities, and also for basic strength training for mid to lower back pain due to lack of exercise and weakening of stomach muscles. I purchased this routine for a client and within two weeks, she has shown marked improvment in mobility, a decrease in lower back pain and a noticable improvement in physical appearence (trimming down)
