You might dread doing them at times, but burpees will work your entire body and get your heart rate up in no time.
To do them, stand up straight then lower into a squat position with your hands on the floor in front of you. Kick your feet back into a push-up position and immediately drop your chest to the floor. Bow your chest up as you return your feet back to the squat position as fast as possible, then jump up into the air as high as you can. Add a little clap for pizzazz, then do it all over again!
You can also do burpees with a full push-up or end in a plank rather than lowering all the way to the floor.
If you get bored with regular burpees, try mixing it up with fun burpee variations like burpee tuck jumps, burpee lateral jumps, and burpee box jumps.
