@craigjackson_: Many struggle with push-ups because they’re not pushing from a position of power. Hands too wide, elbows flared out, and your chest, shoulders and arms can’t do their job. Here’s how to git in the position of POWER: 
Hands under your shoulders. Elbows tucked in close. Then build up in three simple steps: 1. Push-ups on the wall 2. Push-ups on a sturdy chair/ or worktop 3. Push-ups on a low table or stairs 4. Push-ups on the floor The lower you go, the harder it gets. Stay at each level until it feels comfortable, then move down. From 40 onwards, we start losing muscle if we don’t use it. Pushing your own bodyweight is one of the simplest ways to protect it, with no gym and no equipment. Save this and follow for more simple exercises to help you stay strong after 40.
