What the Clock Push-Up Data Reveals
Clock Push-Up is classified in the PlainExercise database as a intermediate-level compound movement with a push force profile, primarily training the Chest with secondary engagement of the shoulders, triceps. The canonical form requires body only, and the movement falls within the strength category. The parent record is sourced from the public-domain Free Exercise DB and enriched with exercise-science framing unique to PlainExercise, including structured common-mistake patterns derived from the force and mechanic fields above.
Within the same primary-muscle cohort, the Chest is trained by 9 catalogued movements in total — meaning any practitioner planning a session has at least 8 alternatives that load the same tissue through different joint angles or equipment profiles. No alternate-equipment variations have been catalogued for Clock Push-Up yet; the canonical form is the documented path. The documented execution runs 6 discrete steps, each one derived directly from the upstream record and reproduced verbatim rather than paraphrased.
Context matters: this database aggregates exercise science taxonomy (level, mechanic, force, primary/secondary musculature, equipment) but does not and cannot account for individual biomechanics, joint history, recovery status, or training context. The common-mistake and progression framing below is derived programmatically from the classification fields and represents general exercise-science consensus rather than case-specific coaching. This is not medical or personal-training advice. Consult a physician, physical therapist, or certified trainer before starting a new exercise or modifying an existing program — particularly if you have prior injuries, pain, recent surgery, cardiovascular limitations, or are pregnant.

Muscle activation profile
Relative recruitment between the primary mover and secondary stabilizers.
Method: muscle counts from Free Exercise DB; relative-share normalization. Not EMG-derived — actual activation varies by load and form.

How to do it
- Move into a prone position on the floor, supporting your weight on your hands and toes.
- Your arms should be fully extended with the hands around shoulder width. Keep your body straight throughout the movement. This will be your starting position.
- Descend by flexing at the elbow, lowering your chest toward the ground.
- At the bottom, reverse the motion by pushing yourself up through elbow extension as quickly as possible until you are air borne. Aim to "jump" 12-18 inches to one side.
- As you accelerate up, move your outside foot away from your direction of travel. Leaving the ground, shift your body about 30 degrees for the next repetition.
- Return to the starting position and repeat the exercise, working all the way around until you are back where you started.
Common mistakes
- Rushing through reps — controlled tempo (2-3s down, 1-2s up) is what drives muscle tension, not raw speed.
- Partial range of motion — moving the joint through its full safe range is what most reliably separates effective from wasted reps.
- Treating a compound lift like an isolation movement — Clock Push-Up recruits multiple joints; bracing the core and engaging stabilizers matters as much as the prime movers.
- Flaring elbows excessively on push movements — tucked elbows protect the shoulder joint and transfer more force into the target muscles.
- Breathing out of sync with the lift — brace and inhale during the lowering phase, exhale on the exertion.
Who this is for
- People with 6+ months of consistent training who can perform basic compound lifts with good form
- People who want to train the Chest and secondarily shoulders, triceps
- People training at home without equipment
Who this is NOT for
- Anyone with acute pain in the joints or muscles involved — pain is a stop signal, not a soreness signal
- People with unresolved injuries in the loaded joints — seek clearance from a physical therapist first
- Anyone with a recent surgery, cardiovascular limitation, or pregnancy complication without physician clearance
Progression path
Once Clock Push-Up feels comfortable with your current load, progress by (a) adding reps until you can complete 12+ per set, (b) increasing resistance by 2.5-5%, (c) moving to harder variations such as single-limb or longer lever versions, and eventually (d) stepping up to expert-level movements that train the same muscle.
See the Progression guide for a full framework on when to advance, and the Compound vs Isolation guide to decide when to prioritize this movement in your program.
Safety notes
- Sharp or joint pain is a stop signal. Muscle soreness during sets is normal; pain is not.
- Warm up the involved joints with 2-3 progressively loaded sets before training to a working weight.
- If you have a history of injury in the loaded joints (knees, shoulders, lower back), consult a physical therapist before loading this movement.
