Cross-Body Mountain Climber

What moves the load, and what it costs
8.0MET
Obliques is the prime mover, with the abs, hip flexors assisting. Adds rotation to the mountain climber and brings the obliques in properly.
Cue: Drive each knee towards the opposite elbow, allowing the trunk to rotate slightly.

SHARED AXIS · SEVEN VALUES FROM ONE TABLE · HIGHLIGHTED ROW IS THIS MOVEMENT
The compendium files cross-body mountain climber under a category, not a lift. Read the ladder as position, not precision: this is heavier work than sitting quietly by a factor of 8.0, and at the top end of what a gym floor produces.
Turning that MET value into a real energy cost
- Map the movement to a published category. The compendium measures categories of conditioning work, never individual lifts, so cross-body mountain climber is filed under Calisthenics (e.g. push-ups, sit-ups, pull-ups), vigorous effort.
- Take the category's MET value — 8.0. One MET is the cost of sitting quietly, so this is 8.0 times resting metabolism.
- Multiply by 3.5 to get millilitres of oxygen per kilogram per minute, the unit the MET is actually defined in.
- Multiply by your bodyweight in kilograms and divide by 200. The result is kilocalories per minute of work.
- Count working minutes only. Under load, not under the roof — a set of eight is about 25 seconds of the hour you were there.
kcal/min = MET × 3.5 × body mass (kg) ÷ 200 Cross-Body Mountain Climber: 8.0 × 3.5 × 70 ÷ 200 = 9.80 kcal/min

What is actually doing the work
| Muscle | Role | What it does here |
|---|---|---|
| ObliquesExternal and internal obliques | Prime mover | Rotate and side-bend the trunk, and resist rotation. The internal oblique on one side works with the external oblique on the other. |
| AbsRectus abdominis | ಸಹಾಯಕ / ಸ್ಥಿರಕಾರಿ | Bends the trunk forward and, more usefully, resists it being extended backwards. Both a crunch and a plank load it — differently. |
| Hip flexorsIliopsoas and rectus femoris | ಸಹಾಯಕ / ಸ್ಥಿರಕಾರಿ | Lift the thigh towards the chest. They drive every leg raise and knee raise, which is why 'ab' exercises often feel like hip work. |
The prime mover produces the movement against the resistance; synergists assist and stabilisers hold a joint still without moving it. An exercise trains the whole muscle it loads — there is no way to work only part of a muscle, and no exercise removes fat from the area around it.
Set up, then earn the rep
Bodyweight. Every rep should look like the first one. The moment it stops looking like the first one, the set is finished.
PATTERN · BRACE
- Set up in a straight-arm plank with the hands under the shoulders and the body in a straight line.
- Brace the trunk and squeeze the glutes.
- Drive each knee towards the opposite elbow, allowing the trunk to rotate slightly.
- Drive one knee towards the chest, then switch legs, keeping the hips low and level.
- Build up speed only once the hips stay still.
- Work for time rather than counting reps.
Where this one breaks down
Not theory. These are the faults you correct on a gym floor, and the correction that actually works.
Hips bouncing up and down.
The trunk is meant to hold still while the legs move. Slow down until it does.
Hands creeping forward.
Keep them under the shoulders or the shoulders take a beating.
Treating it purely as cardio.
It is a moving plank first. If the plank fails, the cardio is not worth much.
Regress it, or progress it
Regress — earn it first
Progress — the next demand
Prescription: load, reps, rest
Read off the goal, then hold the technique constant as the load climbs. Derived from the movement's mechanics, not invented for this page: a explosive movement is destroyed by fatigue, so reps stay low and rest stays long.
| Goal | Sets | Reps | ವಿಶ್ರಾಂತಿ | Notes |
|---|---|---|---|---|
| Power | 4–6 | 2–5 | 2–3 min | Every rep is fast or the set is over. Fatigue kills the quality this trains. |
| Athleticism | 3–5 | 3–6 | 90–120 sec | Quality of landing matters as much as height or distance. |
| Conditioning | 4–8 | 8–12 | 45–60 sec | Used this way it is cardio, not power work — pick one intent per session. |
| ಆರಂಭಿಕ | 2–3 | 3–5 | 2 ನಿಮಿ | Learn to land softly before you try to go higher or heavier. |
Time under load, in kilocalories
Read these as minutes of work, not minutes in the building. A set of eight takes about twenty-five seconds; the rest of the hour is rest, chalk and queueing.
Mapped category: Calisthenics (e.g. push-ups, sit-ups, pull-ups), vigorous effort — 8.0 MET. That is the published category this movement is filed under, not a measurement of this specific lift.
Worked at 8.0 MET × 3.5 × 70 kg ÷ 200 = 9.80 kcal per working minute for a 70 kg adult. Scale it by your own bodyweight; the equation is linear. The full activity dataset lives at BurnLab.

If the rack is taken
Substitutes train the same prime mover through the same pattern with different kit. Computed from the muscle and pattern data on this card, not hand-picked to fill a grid.
This one needs no equipment at all, which is why it belongs in every travel and home programme. Every no-equipment movement is listed together.
Where it sits in a week
One movement is not a programme. The twelve templates put these in order, including 6 that need no gym at all.
The questions that come up on the floor
What muscles does the cross-body mountain climber work?
Cross-Body Mountain Climber is an explosive movement in which the obliques is the prime mover, assisted by the abs, hip flexors. Rotate and side-bend the trunk, and resist rotation. The internal oblique on one side works with the external oblique on the other.
Is the cross-body mountain climber good for beginners?
Not on day one, but it is reachable within a few weeks. It rates 3 out of 5 for technical demand. Work up through the easier versions listed on this page first, starting with the side plank.
What can I do instead of the cross-body mountain climber at home?
Nothing is needed — the cross-body mountain climber already requires no equipment at all, which is why it belongs in any home programme.
How many sets and reps of the cross-body mountain climber should I do?
For muscle size, 3–5 sets of 3–6 with 90–120 sec rest. For strength, 4–6 sets of 2–5 with 2–3 min rest. In your first month, 2–3 sets of 3–5, stopping well short of failure. Total weekly hard sets per muscle group matters more than the exact rep number in any of these ranges.
Does the cross-body mountain climber burn fat from the obliques?
No. No exercise removes fat from the area it trains — spot reduction has been tested repeatedly and does not happen. Training the obliques builds the muscle underneath; where body fat is lost from is decided by an overall calorie deficit and by your genetics, not by which exercise you chose.
Muscle roles follow standard kinesiology references and are described by joint action rather than by gym convention — see how this site is built. Energy figures are derived from the 2024 Adult Compendium of Physical Activities. Every reference is named and dated on the ಮೂಲಗಳು page. General information only — not medical or coaching advice. Load, form and progression should be adjusted to your own experience and any injury history. When in doubt, get coached in person.
