Bone mass generally peaks around the age of 30-35, and then starts to slowly decline at around age 50 in women (60 in men) when you start to lose bone mass faster than your body can grow it back.

You may see these changes start as early as your 30s, but most people see the biggest changes between their 40s and 50s. 1  A recent study concluded that total muscle mass decreases by nearly 50 percent for people between the ages of 20 and 90. On average, people lose about 30 percent of their strength between ages 50 and 70, and another 30 percent of whatâs left per decade after that. Generally, people lose about 1 percent of their lean muscle mass per year after age 40. The following four types of muscle weakening (called atrophy) become more common as people age, and each type responds differently to strength training.
