3. Alternating Push Ups
This is basically the kind of push up which affects your core strength. You start off in a regular plank position except that your right hand or left hand should be placed a bit above the other hand. Depending on which hand you place above, you lift the opposing leg off the floor and then lower yourself to perform the push-up. The idea is that you are in an unstable position so your core area works more to keep you balanced. Repeat this process with the other hand and the other leg. Make sure you don’t overdo it as it can have a negative impact on your shoulder blades.
