Plank that runs in place

Mountain Climber

Hold a plank. Drive one knee toward your chest. Switch. Your hips stay a table, not a pogo stick.

Hunter: I count a knee drive each side. If my butt shoots up, I slow down. Fast and ugly is not cardio. It is a broken plank.

Cues

Hands under shoulders. Body one board.
Drive a knee toward the chest. Foot stays light.
Switch. Hips stay level. Do not bounce.
Neck long. Do not crane at the wall.
Breathe. Stop when the plank dies.

Setup

Floor or a sturdy bench for an incline if the floor plank is too much. 3 sets of 20-30 total knees, or 10-15 each side. Rest about 30 seconds. Dorm Engine day puts these after burpees.

Keep the plank

If the line breaks, elevate the hands or slow the pace. The climber is a moving plank. When it becomes a scramble, the set is over even if the clock is not.

How I log them

Total reps or each side. Pick one for a month. I use each side so the number matches lunges in my brain. Engine does not care. You should, so next week compares.

Incline version

Hands on a bench. Same cues. Easier on the wrists and the midline. Log mountain climbers and put incline in the notes if you want the history to stay honest.

Common misses

Piking into a downward dog. Letting the hips sag. Slapping the feet so loud the RA knocks. Also: 100 sloppy reps because a timer told you to.

FAQ

Cross-body or straight?

Straight knee toward the chest is the default. Cross-body is a different twist. Pick one.

Time or reps?

Reps on this page. If you want a clock, log duration as a different session note. Do not mix them week to week.
