You begin standing tall, dip quickly into a shallow quarter squat, and then explode upward for maximum height, landing softly back on both feet. Pinning the hands to the hips removes the arm swing that normally contributes to jump height, which isolates the work to the legs and hips. This makes the variation a clean way to measure raw lower-body power and to track how it changes over time. Because the arm swing is eliminated, this movement is a staple in athletic testing settings, where coaches use it to assess explosive strength without the extra contribution from the upper body. The quick dip before the jump — the countermovement — lets the muscles stretch briefly and then recoil, tapping into the stretch-shortening cycle. That rebound effect is exactly what most jumping, sprinting, and change-of-direction actions rely on, so training it carries over well to sport. The main drivers are the quadriceps and glutes, with the hamstrings controlling the descent and stabilizing the knee, and the calves finishing the jump with a strong push through the ankles. The core works isometrically the whole time: with the hands pressing into the hips, there is nowhere to hide any sway or lean, so the trunk has to hold the spine quiet through the dip, the flight, and the landing. Setup matters more than it looks. A shoulder-width stance with even weight across both feet gives you a symmetrical base, and keeping the hands firmly on the hips prevents the shoulders from sneaking into the movement. If the torso pitches forward or the hands drift, the jump is no longer a fair representation of leg power, so treat the position as part of the exercise, not a formality. To execute it well, think fast down, fast up. The dip should be quick and shallow — around a quarter squat depth — with no pause at the bottom. Hesitating between the dip and the jump kills the elastic rebound and turns the movement into a sluggish squat jump. Drive the floor away through the whole foot, extend the hips, knees, and ankles together, and land on the balls of the feet before settling the heels. This exercise suits athletes testing their vertical, lifters who want a low-fatigue power primer before squats or deadlifts, and anyone training jump mechanics with a strict, repeatable standard. Because it requires no equipment, it can be done almost anywhere, though a firm, non-slippery surface and enough ceiling clearance are non-negotiable. Keep the volume modest — a handful of quality reps per set with full recovery — since fatigue degrades jump height quickly and defeats the purpose of the drill. ## Instructions 1. Stand with your feet about shoulder-width apart on a firm, flat surface, toes pointing forward or slightly out. 2. Place both hands flat on your hips with elbows out to the sides, and keep them there for the entire set. 3. Stand tall and take a breath, bracing your trunk so your ribs stack over your pelvis before you initiate any movement. 4. Begin the countermovement with a fast, shallow dip: push your hips back and bend your knees to roughly quarter-squat depth in one fluid motion. 5. Without pausing at the bottom, drive forcefully through the whole foot and extend your hips, knees, and ankles to jump straight up for maximum height. 6. Keep your torso upright and your hands glued to the hips during flight; avoid leaning, twisting, or reaching with the arms. 7. Land on the balls of both feet at the same time, then let your hips and knees bend to absorb the impact softly. 8. Stand fully upright, re-brace, and reset your stance before starting the next repetition. 9. Exhale sharply as you explode up, and inhale during the brief reset between jumps. 10. Rest 30-60 seconds or more between reps when testing maximum jump height, so each attempt is performed fresh. ## Tips & Tricks - If your jump height drops on later reps, stop the set — countermovement jumps are a power expression, and grinding out fatigued reps trains nothing useful. - A common fault is dipping too deep. Because your hands are on the hips, a deep squat often rounds the lower back and slows the transition; keep the dip to roughly a quarter squat. - Do not pause at the bottom of the dip. The whole point of the countermovement is the rapid switch from lowering to exploding, so aim for a rebound, not a squat jump with a stop. - Watch that your hands stay pressed on the hips during flight. Hands that drift forward or swing mean the arms are contributing, which contaminates the measurement. - Keep your weight even across both feet through the dip. Shifting to one leg changes the force profile and adds uneven landing stress to one knee and hip. - Land quietly. A loud, stiff landing with straight legs signals that your hips and knees are not absorbing force; cue yourself to land toes-first and sink into the hips. - If the ceiling is low or the surface is hard, reduce jump intent rather than skipping the landing mechanics — controlled submaximal jumps are still valuable. - For testing, use the same foot position and surface each session, since stance width and flooring both change measured jump height. - If you feel your heels lifting or ankles collapsing inward on landing, slow the tempo down and practice the dip and landing separately before jumping at full effort. ## Frequently Asked Questions ### Why are the arms held on the hips during the Countermovement Jump Arms On Hip? Fixing the hands on the hips removes the arm swing, which normally adds noticeably to jump height. This isolates the effort to the legs and hips, making the jump a cleaner measure of lower-body power and easier to compare between sessions. ### Which muscles does the Countermovement Jump Arms On Hip work most? The quadriceps and glutes produce most of the force, supported by the hamstrings during the dip and the calves at takeoff. The core also works continuously to keep the trunk stable with the hands fixed on the hips. ### Is the Countermovement Jump Arms On Hip suitable for beginners? Yes, as long as you start with submaximal effort and focus on the dip-and-rebound timing and soft landings. Beginners should build comfort with landing mechanics before attempting maximum-height jumps. ### How deep should the dip be before jumping? Aim for a shallow quarter squat — deep enough to load the hips and knees, but shallow enough to reverse quickly. Dipping too deep slows the transition and loses the elastic rebound the countermovement is designed to use. ### What is the most common mistake in this jump? Pausing at the bottom of the dip is the biggest one, because it turns the movement into a much slower squat jump. Letting the hands leave the hips or swinging the arms are also frequent faults that change what the jump measures. ### How is the Countermovement Jump Arms On Hip different from a regular vertical jump? A regular vertical jump uses a free arm swing, which usually produces a higher jump. With arms on the hips, the score reflects leg and hip power alone, which is why this version is common in testing protocols. ### How many reps and sets should I do? For testing, 2-3 maximum-effort jumps with a minute or more of rest between them is typical. For training, keep sets to a handful of quality reps and stop when jump height or landing quality noticeably drops. ### What can I use instead of the Countermovement Jump Arms On Hip? A squat jump with a pause at the bottom trains similar muscles with less reliance on the stretch reflex, and a standard countermovement jump with free arms is a good progression once landing mechanics are solid. ### What surface and footwear are best for this exercise? Use a firm, non-slippery surface such as a gym floor or court, and wear cushioned athletic shoes with stable heels. Avoid soft mats or uneven ground, which make landings less predictable. ### Is landing from the jump hard on the knees? Landing is well tolerated when you absorb it by bending the hips, knees, and ankles and land toes-first with both feet together. If you have current knee discomfort, reduce jump height or consult a professional before doing maximal jumps.
