Remember, the key is moderation. Walking can be done either on a treadmill or outdoors on a level terrain with properly fitted and supportive footwear. Biking Exercise biking is available in a variety of settings. Stationary bikes come in many sizes and shapes and offer multiple features such as movable or alternating handlebars, adjustable resistance, and standard or recumbent seating. In general, bikes which have stationary arm support are preferred, and any bike chosen should be set at little or no resistance.
Recumbent bikes have seats which look like a chair and allow the user to lean back with support.
They are available at most health clubs and keep the upper body in a more upright position during exercise, offering additional support for the back. Mild, low-impact aerobics should be performed on a level surface and not involve benches or steps. These exercises improve both cardiovascular conditioning, muscle and joint range of motion, flexibility, balance, and coordination skills. Good structured routines include a stretching component at the beginning and end of the session. These exercises will need to be modified depending on the muscles involved.
