Set your timer for 10 mins. Each minute you need to perform 15 mountain climbers and 5 burpees. If you finish before the minute is up you get a break. If you don't you keep going :) Just make sure you have proper form. If your form starts to fall apart pause the timer and take a break. My favourite timer is GymBoss!
Warm up for 5-10 minutes before you start and then cool down and stretch when you're done!
