Keep hands at hip level. Bring knee to hand and alternate. Each knee-to-hand touch counts for one repetition.

Start in a plank on your hands and your feet on sliders. You can use a paper plate on carpet or wood if you are in your house. Slide one foot at a time as close to your hand as possible. As your foot is sliding focus on only moving your hips up and down a few inches to maximize abdominal engagement.

Start in a pushup position, your bodyweight supported by your hands and toes. Bring one leg towards the opposite elbow, until the knee is under the hip. Explosively reverse the positions of your legs, (like you are running in a pushup position). Repeat.

Straight arms and legs throughout the jumping jack motion. Hands must touch above head, then squat to touch toes at bottom of the motion. Each clap above head is one rep!

Lateral hop must be 4ft wide in distance. Hand must touch opposite foot. Swing your arms as you hop from side to side, making sure to maintain balance. Each time you tap a foot it counts as a rep!

Stand tall with your feet hip width apart and knees slightly bent. Lower yourself until your knees reach a 90 degree angle and you are in a full squat position, then quickly drive through your heels upward and jump as high as possible. Make sure to keep a bent, soft knee as you land. Repeat.
