The most common form of strength training is resistance training, weight training or weight lifting. Resistance can be achieved by simply lifting your own legs and arms or trunk against gravity.
More advanced training includes using equipment such as elastic bands, dumbbells or machines.
Target the muscles of the hips, spine and wrists. Include muscles important in maintaining proper body mechanics by strengthening the front of the thighs, the buttocks, and the stomach. Exercise all major muscle groups to improve your overall strength. Avoid twisting motions and flexion of the spine such as traditional sit-ups. This refers to the frequency of exercise.
