If one is trying to develop muscle there are a number of muscle building routines that will accomplish this. It is believed that the best way for one to build muscle is through the use of weights and weight lifting programs. If one does not have access to the proper equipment, local gyms offer full weight training equipment.
Isometrics.
The best way to exercise without building "short muscles" is swimming, running and other cardiovascular exercises. The best possible exercise for your joints, while toning your body is swimming.
muscle relaxers work best
There are many places to find total gym workout routines. Magazines like 'Shape' and 'Muscle and Fitness' have great workout routines to follow, and sites like 'Golds Gym' online have great routines too.
The best muscle toning routines depend on a number of factors including, which parts of the body need toning, how fit the person concerned is and how long a work out is needed. Full body work outs are great for toning all parts of the body.
The best weight training routines to help bulk up is low weights, jogging, running, walking, sit ups, twirls, curls, squats and there are other exercises as well.
Your best bet would be a Bowflex machine. They have multiple exercises and are great at building muscle. You can probably buy them on Amazon. I hope this helps and good luck.
Squat.
this would be to use light weights you are still working your muscle but not to bulk them up
As you cannot do squats, the next best is kickbacks. If these also give you problems then simple squeeze-hold repeated routines will help.
Try combining strength building and cardio training exercises.
Testosterone, obviously.
