From a high plank you drive your knees toward your chest, one after the other. This mountain climber counter follows each hip and calls out every rep, so you can keep your pace.
Choose alternating mode, where each knee drive adds one to your total, or one-leg mode, where the coach calls the switch. Get into your high plank during the five-second countdown.
Phone setup
Rest the phone sideways (landscape) on the floor about 2 meters (6 feet) away, a little toward your feet and turned slightly toward you instead of square to your side. That keeps both legs in view. Your whole body, head to feet, needs to be in the frame.
Get into a high plank with your hands under your shoulders.
- Set your plank before the countdown ends, then check the preview shows your head, hands and feet inside the frame.
Form cues
- Hands under your shoulders. Stacked wrists keep the plank steady while your knees drive.
- Drive the knee to your chest. Pulling one knee toward your chest is the far position of the rep.
- Switch legs at a steady pace. Alternate smoothly so each knee gets a full drive before the next.
- Send the leg back. Returning the knee to the plank completes the rep.
Common mistakes
- Bouncing your whole body. Let the legs do the moving while your shoulders stay over your hands.
- Short knee drives. A knee that never gets driven toward your chest doesn't reach the far position and isn't counted.
- Piking your hips up. Lifting your hips into a peak turns the drill into a stretch. Keep your back flat as each knee drives in.
How FitnessBruh counts it
The counter reads the angle at each hip, from shoulder to hip to knee. In the plank with a leg back is the start, a knee driven toward your chest is the far position, and driving it back completes the rep.
In alternating mode each knee drive is one rep, and either leg adds to the total. One-leg mode follows the leg you pick instead: the coach calls the switch with a short count-in, and the set ends after both legs.
Counting begins once you've been down in the plank for a moment, so getting into position adds no rep. Get up mid-set and it stops until you're back down in position. Your shoulders and hips need to be steadily in view before it begins.
FAQ
How does the mountain climber counter count reps?
In alternating mode each knee drive counts as one rep, so left and right both add to your total. One-leg mode follows the leg you pick instead.
Does getting into the plank add a rep?
No. Counting only begins once you've been down in the plank for a moment, so setting up adds nothing to your total.
Where does the phone go for mountain climbers?
On the floor, sideways (landscape), roughly 2 meters (6 feet) away, with the phone angled a little toward your feet and turned slightly toward you. That way both legs stay in view.
