To do burpees, start in a squat position with your hands on the floor. Make your way into the top of a push up position and do a push up, then get your feet back underneath you and jump up. Get back down into squat position and repeat. (You’re right. Everyone hates burpees!)
Make this easier by not doing the push up. Just go to the top of the push up position, but don’t actually do the push up. Then get your feet back underneath you from there. The point of this is to get your heart rate up – not necessarily to do tons of push ups.
Make this harder by going faster or doing a wider stance push up.
