If a machine isn't practical, you can add jump rope workouts or other calisthenics to your exercise plan.
Weight bearing exercises and strength training, such as lifting weights or calisthenics, build muscles.
When you find yourself with time on your hands, instead of sitting down and watching television, try five to ten minutes of calisthenics.
Perform calisthenics for specific muscle groups (such as push ups and jumping jacks) to build endurance.
Turn the disadvantage to an advantage by making it a point to master bodyweight-only exercising and alternate between equipment and calisthenics workouts on a regular basis.
