2. Wall Push-Ups
Proper push-ups can be difficult for even younger adults that are in good shape, so here’s a slightly easier version that may be easier on your joints. Healthline.com says “modified” push-ups against a wall are a good way for seniors to build strength.
To do these wall push ups, stand facing a wall with your toes 12 to 18-inches from it. Then lean forward slightly and place your palms flat against the wall at shoulder height. Carefully ease yourself toward the wall by bending at the elbows, trying to get your nose as close to the wall as you can (don’t strain). Gently push yourself back to the starting position, says the source. Try 10-reps of this one, it adds.
