Gaining muscle and strength
Older people can gain significant muscle mass with resistance training even though the response is not the same as in young people. Once a certain level has been reached, we older guys need more training than the young to preserve our gains.

“We conclude that older adults require a higher dose of weekly loading than the young to maintain myofiber hypertrophy attained during a progressive RT program, yet gains in specific strength among older adults were well preserved and remained at or above levels of the untrained young.”
