Push-ups simultaneously affect shoulders, chest, triceps and abdominal muscles, helping to lift a large part of the body's weight. This is also a test of balance, flexibility and stability of shoulders - factors that often decline with age.
If you can perform the movement with full amplitude and correct technique, it shows that muscles and connective tissue are still working well.
Basic push-ups
Start in a high plank position, placing both hands under your shoulders, keeping your body straight from head to heel. Tighten your abs, lower your chest near the floor by folding your elbows, then push yourself back to your starting position.
Push-ups on a chair
Place both hands on a sturdy chair, shoulder-width apart. Step back to form a straight line from head to heel. Lower your body until your chest reaches your elbows, then push yourself up.
Push-ups with walls
Stand about arm length apart from the wall, place your hand on the wall shoulder-length. Bend your elbows to lower your chest near the wall, then push back to the starting position with slow motion and control.
