For many people, variety is the key to a successful program, so don't limit yourself to the same aerobics video or walking trail day after day if you don't want to. Your prescription may include exercises from each of the following groups.
Aerobic exercises.
Aerobic exercises use low- to moderate-intensity continuous motion to increase your breathing and heart rate and improve your cardiovascular fitness — the health of your heart, lungs and circulatory system. Aerobic activities cover a range of exercises, including walking, biking, swimming, hiking and aerobic dancing.
Strength exercises.
Strength (resistance) exercises build your muscle strength and endurance, which in turn help improve your posture, balance and coordination. These exercises involve working with resistance (pulling or pushing against a force) to increase muscle force-generating capabilities. These exercises can also help build muscle size and improve muscle definition. Activities include lifting free weights, using weight machines, working with resistance bands and using your body weight in exercises like push-ups.
Core stability exercises.
A subset of strength exercises, core stability exercises strengthen and stabilize your trunk muscles. Building strength in these muscles supports your spine, improves posture and balance, promotes better sports performance and may help prevent back injury. Examples of this type of activity include Pilates and using a fitness ball.
Flexibility exercises.
Flexibility exercises increase your range of motion, make your muscles more limber and may help reduce the risk of injury. They also improve your posture and aid in your body's recovery from vigorous activity or exercise sessions. Activities which improve flexibility range from simple stretching exercises to yoga.
Balance exercises.
Balance exercises help you maintain balance, reducing your risk of falls and injury. They also help improve performance. Activities include tai chi, yoga, weight shift and single-leg balance reach exercises. Many strength exercises can be modified to improve balance.
