Reason 2 To Do Pushups

Core Strength When you perform pushups, your spine should remain neutrally curved and rigid so that any load is distributed safely through it. If your back should sag, your lumbar spine will become hyperextended, which can lead to injury. Keeping your spine properly aligned is the job of your core -- the muscles around your midsection. Although primarily considered an upper body exercise, pushups also strengthen your core muscles -- specifically your rectus abdominus and transversus abdominis.
