For people over 55 years old, exercise performance expectations need to be adjusted to suit physiological changes with age as muscle mass and recovery ability gradually decrease.
The practical standard for healthy people aged 55 - 65 is that men can perform from 15 - 25 repetitions of controlled sit-ups for 1 minute, while women reach about 10 - 20 repetitions.
At the advanced level, men can perform over 30 repetitions and women over 25 repetitions, provided that the technique is correct and movement control is good. However, the quality of the movement is more important than speed.
After the age of 55, what needs to be focused on is not the number of repetitions but maintaining proper breathing, controlling the spine and performing painless exercises. Abdominal flexion ability may be slightly reduced due to rapid fibromyalgia, reduced body flexion strength and slower recovery.
