Also, repetitive exercises of certain muscle groups can lead to injury. So update your routine every two to three months. Cross-training is another way to keep exercise varied and interesting. For instance, dedicate Tuesdays and Thursdays to walking and low-impact aerobics, and Mondays and Wednesdays to swimming and riding a stationary bike. Interval training also keeps your exercise routine varied.
Interval training consists of short bouts of exercise alternating with brief recovery sessions.
For example, interval training in a walking program could involve walking briskly for the first half mile and then walking at a lighter intensity for the next quarter mile. Alternating intense activity with rest or recovery periods can increase your aerobic fitness. The length of the exercise and recovery intervals will depend on your individual goals. Individuals who diet without exercising tend to have a more dramatic decrease in lean body mass than those individuals who do exercise. I have found that most of my clients enjoy the feeling of strength and toning that occurs with resistance training.
