Yes, strength-training should be a key part of your fitness plan if you’re over 40. Unfortunately, too many people blame aging for their decreased fitness levels and loss of functional ability. This is a mistake. While some physiologic changes are normal as we age, adults 40 and over respond to exercise and strength-training similarly to younger adults. Many of the ill-effects of a sedentary lifestyle such as high blood pressure, heart disease, type 2 diabetes , and osteoporosis can be avoided (and is some cases even reversed) when you incorporate a healthy lifestyle including strength-training. In addition, strength-training can help you prevent significant reductions in muscular strength, flexibility, endurance, balance, and coordination.
When beginning a strength-training regimen it will be important to start slow and progress according to your fitness level. Start with body-weight exercises or light weights to help your body become accustomed to strength-training. As your fitness and strength improve, you can increase the intensity of your exercise routine.
