This claim says that light weight training doesn't really help older adults get bigger muscles, move faster, or get up and go quicker after doing it twice a week for 12 weeks.

For older adults doing light weight training, pushing muscles to complete exhaustion doesn't give extra benefits like more strength or muscle growth compared to stopping before exhaustion, since both ways work about the same after 12 weeks.

Older adults doing light weight lifting twice a week for 12 weeks can get about 20% stronger, even if they don't push themselves to their absolute limit every time.

Light weight training helps older people move better by making it easier to stand up from a chair and walk faster after doing it twice a week for three months.

Gentle weight training done slowly and steadily twice a week for 12 weeks can make older adults' thigh muscles thicker and stronger.

Even people in their 50s and 70s can get much stronger and activate their muscles better after 12 weeks of heavy weight training — age doesn’t stop them from improving.
