This great workout for your kids is targeted to help them build their strongest arms and chest. 2 supersets at the beginning will allow them to warm up their body while having fun with some of the faster paced cardio movements.
Second part of the workout will bring them to the floor and challenge their arms and back in isolation exercises such as planks, swing backs and up downs, while still getting a chance to move a little bit faster with mountain climbers and kickbacks.
