It may be simple, it may not require any equipment, but the push up is one of the most effective bodyweight exercises. This compound movement works a multitude of upper body muscles with the main focus on the chest, shoulders, triceps and core. If stronger pecs are therefore what you’re after, then they should be a staple in your programme.
But, let's be honest, simple doesn’t equate to ‘easy’ and learning how to master the push up with the correct form is far from that. Do it wrong and you won't reap its full benefits, not to mention you're increasing your chances of injury.
