Isometric Wipers are a bodyweight chest hold done in a push-up position: you press both hands inward against the floor without letting them move, loading the pectoralis major sternal head (lower chest) with sustained tension. The clavicular head, anterior deltoid, biceps brachii, brachialis, brachioradialis, and triceps brachii work as synergists. It builds pressing strength and chest control with no equipment at all.
Isometric Wipers: So führst du sie aus
- 1Set up in a push-up position with your hands slightly wider than shoulder-width, fingers pointing forward, and your body in a straight line from head to heels.
- 2Bend your elbows and lower until your chest is a few inches off the floor and your elbows sit at roughly 90°, then stop and hold that position.
- 3Brace your core and squeeze your glutes so your hips stay level — no sagging lower back, no piking upward.
- 4Drive both hands into the floor and pull them toward each other, as if wiping the floor inward beneath your chest. Press hard enough that the effort is maximal, but keep your hands still.
- 5Keep your elbows tracking at roughly 45° from your torso rather than flared straight out to the sides.
- 6Hold the contraction for 3–10 seconds, breathing steadily rather than holding your breath.
- 7Release the inward force under control, press back up to the top of a push-up, and rest briefly before the next hold.
Technik-Tipps
- The inward force is the whole exercise, not the position — press as if you are trying to drag the two halves of the floor together beneath your chest.
- Set your hands roughly under your lower chest rather than under your shoulders, so the inward line of force matches the sternal fibers.
- Change the difficulty with depth: the closer your chest is to the floor, the longer the lever and the harder the hold. Stay a few inches higher to make it easier.
- Build hold time before adding sets — go from 3–5 seconds to 8–10 seconds per rep at the same intensity, then add a set.
- Use these at the end of a chest session or between sets of pressing work; they fatigue the muscle hard but stay light on the shoulder and elbow joints, so they will not eat into your heavy sets.
Häufige Fehler
- Pressing straight down into the floor instead of inward, which turns the exercise into a push-up plank — the triceps and shoulders hold you up while the sternal chest fibers barely work.
- Letting the hips sag or pike during the hold, which pulls the load off the chest and stacks stress on the lower back.
- Flaring the elbows out to 90° from the torso, which loads the front of the shoulder joint and gives the sternal chest a worse angle to pull from.
- Holding your breath for the whole set, which spikes blood pressure and brings on fatigue faster than the muscle itself would.
- Counting the hold too fast — an eight-count that is really four seconds halves your time under tension, which is the main variable this exercise has.
Häufig gestellte Fragen
What muscles do Isometric Wipers work?
They primarily target the pectoralis major sternal head (lower chest). The pectoralis major clavicular head, anterior deltoid, biceps brachii, brachialis, brachioradialis, and triceps brachii act as synergists, holding the push-up position and assisting the inward pressing force.
What is the difference between Isometric Wipers and a regular push-up?
A push-up is dynamic: your joints move through a full range and the load is your bodyweight. Isometric Wipers are static — the joints do not move, and the load comes from how hard you press your hands inward against a floor that will not move. That lets you work the sternal chest fibers hard at one fixed angle.
How long should I hold each Isometric Wiper rep?
Start with 3–5 second holds and build toward 8–10 seconds per rep as you get stronger. Keep the inward pressing force near maximal for the whole hold — a long, passive hold is worth less than a short, hard one.
Are Isometric Wipers good for building chest muscle?
They build strength well and can add some size, but isometric work carries over mainly to the joint angle you train, roughly 15–20° either side of it. Use them to reinforce chest activation and target a weak point in your pressing range alongside full-range work, not instead of it.
Can I do Isometric Wipers if I am a beginner?
Yes, as long as you have the baseline strength to hold a stable push-up position. If a full plank is difficult, drop to your knees to cut the load, then move to the standard position once you can hold it with a flat back for at least 10 seconds.
