Training effect
Immediate demand
10 minutes, intensity 3 of 5. Today the limiter is 24 cross-body mountain climbers.
Intended stimulus
The same capacity work, with movements you can repeat for the whole clock. On this workout that is 12 sprawls and 24 cross-body mountain climbers.
Repeated practice
Repeat the same workout and compare the score. What can change over weeks is how long that pace lasts. One time through does not produce that change.
Body-composition context
Body weight changes with the rest of how you eat and train. This workout is one piece of work on one day.
Expected feel
24 cross-body mountain climbers is where the round gets hard. The other movements still have to be finished after it.
Pacing
Rotational core engagement while heavily taxing the lungs.
24 cross-body mountain climbers is where the round gets long. That set is where a planned break belongs. If that set falls apart, shorten the sprawls on the next round rather than rushing it.
The movements
Sprawls
Keep a wide stance. Landing with your feet outside your hands reduces the distance your hips have to travel and speeds up the transition to standing.
What not to do. Landing the plank with the hips high instead of level with the shoulders.
Cross-Body Mountain Climbers
Because of the rotation, these are slightly slower than standard mountain climbers. Focus on the hard muscular contraction rather than pure foot speed.
What not to do. Reaching the elbow down to the knee instead of driving the knee across.
Why these movements
The work moves through the full body and the midline instead of sitting on one muscle.
Scaling
Keep the round short enough to repeat. Drop reps so you can stay moving, rather than resting the round into a different workout.
Sprawls
- Step the feet. Step back and step in instead of jumping. Same shape, no impact.
- Hands elevated. Hands on a bench or step so the floor never comes all the way up to you.
- No jump at the top. Stand tall and reach instead of leaving the floor.
Cross-Body Mountain Climbers
- Low impact. Keep one foot down throughout — march the pattern instead of running it.
- Slower cadence. Same movement, fewer beats per minute. Cadence is the dial, not the shape.
Mistakes and who it is for
- Opening the sprawls at a sprint makes the cross-body mountain climbers the piece that falls apart.
- Resting until you feel fresh between movements removes the point of keeping them in one round.
- Letting 24 cross-body mountain climbers fail before you break it is how the next round gets longer.

Scoring and progression
Work through the movements in the order listed, then start the next round. Your score is the number of complete rounds plus any reps of the round you were partway through when the clock hit zero — written as rounds plus reps, so seven full rounds and twelve reps is7+12.
Progression is repeating this workout and comparing that score. The page does not promise a change from one time through.
