When your group fitness instructor commands you to drop down and give them twenty push-ups, you might cringe a little bit (or, a lot). If ordinary push-ups aren't challenging enough, it's time to switch things up. PumpUp member @elisesbodyshop demonstrated 6 different push-up variations that you can try at home. The beauty of these moves is that they don't require any equipment at all. Try these push-up variations regardless of your circumstances: whether you're rolling out of bed or rolling around sand at a beach.
