Strength-training exercises are quite possibly the most important type of exercise to keep you fit. The older you are, the more important they become because without them your muscle tone and strength will decrease with each passing year.
Unfortunately, the vast majority of Americans over the age of 45 (75 percent) do not engage in any strength-training exercises at all, which puts you at an increased risk of weakened bones (osteoporosis), age-related muscle loss (sarcopenia), limited range of motion, loss of functional movement, aches, and pains.
