Mountain climbers
Heart and lungs; core, shoulders and hip flexors.
How to do it
- Get into a high plank, hands under your shoulders and body straight.
- Bring one knee towards your chest without raising your hips.
- Switch legs with a small jump, as if running on the spot.
- Keep the rhythm for the length of the set.
Cues
- Shoulders over your hands.
- Hips level with your shoulders, don't raise them.
- Abs tight.
Common mistakes
- Raising your hips.
- Dropping your head and sinking into your shoulders.
- Bouncing out of control.
If your wrists bother you, put your hands on a bench or a step; it also makes it easier.
