Jumping Jack
There’s a reason jumping jacks have long been a staple of high school gym class. This explosive move is a great way to improve cardiovascular endurance and also engage the core, shoulders, back, and calves.
Stand with feet together and arms by sides. Engage the core and soften the knees.
Jump up as you spread your feet wider than the shoulders and raise your arms overhead. Land with feet spread and arms up. Jump again, bringing your feet together and returning your arms to the sides. Repeat.
Trainer Tip
Try to remain in the “ready” position, on the balls of the feet with a soft bend in the knees.
