Try this equipment-free Core & Cardio drill as a total body finisher, or save it for a day when you can't get to the gym!

Here's the drill:
20sec/movement x 3 movements = 1min/round.
No rest between rounds.
A. Mountain Climbers
B. Plank Switch Lunges
C. Power Jacks

FORM:
[Mountain Climbers]
- Shoulders stacked over hands.
- Press all 5 fingers of each hand into floor to avoid overloading wrists.
- Keep hips at shoulder height.
- Pull knees forward toward the space between your elbows.
- Keep that belly pulled tight!
[Plank Switch Lunges]
**Note: You DO NOT have to jump if this is new to you: alternate stepping each foot forward & back instead if this is new/too advanced.**
- The foot that comes forward should land flat, (heel is on the floor!), and ideally should land directly beside your hand.
- Keep your lower belly super tight and avoid letting your lower back arch as you land.
[Power Jacks]
- When you jump your feet apart, your knees bend to a squat when you land.
- When you jump your feet together, your knees bend to a squat when you land.
- When you land from either jump, your knees should be stacked over your ankles as you land - avoid letting your knees collapse inward.
- Land soft from your jumps!
