Tuck Jump

Definition

The tuck jump is a bilateral plyometric exercise where you jump vertically and pull both knees toward your chest at the peak of the jump. It is one of the most demanding bodyweight plyometrics, requiring explosive lower-body power, hip flexor strength, and core control. For HYROX^® athletes, tuck jumps develop the explosive power and reactive strength that improve running speed, burpee broad jump performance, and transition zone acceleration.

Technique & Form

1. Stand with feet shoulder-width apart, arms at your sides. Brace your core.
2. Dip into a quarter-squat, swinging your arms back, then explode upward by extending your hips, knees, and ankles simultaneously while driving your arms upward.
3. At the peak of the jump, pull both knees toward your chest using your hip flexors and core. Your thighs should reach at least parallel to the floor.
4. Release the tuck and extend your legs to land softly on the balls of your feet, immediately bending your knees to absorb the impact.
5. Reset fully between reps (1-2 seconds) or flow directly into the next jump for a continuous set. Perform 5-10 reps per set.

Muscles Worked

• Primary: Quadriceps, glutes, calves (jump), hip flexors (tuck)
• Secondary: Hamstrings, rectus abdominis
• Stabilizers: Ankle stabilizers, core musculature, adductors

Common Mistakes

• Not pulling knees high enough: A half-tuck reduces the explosive demand. Drive your knees aggressively toward your chest at the peak of each jump.
• Hard landing: Slamming into the ground with straight legs risks joint injury. Land softly on the balls of your feet with bent knees.
• Too many reps: Quality degrades rapidly with fatigue. Keep sets to 5-10 reps with full recovery between sets.

Benefits

• Maximum bodyweight explosive power development
• Trains the stretch-shortening cycle for faster ground contact during running
• Develops hip flexor power for running knee drive
• High metabolic demand for conditioning in short time frames

HYROX^® Context

Tuck jumps build the explosive power used at the Burpee Broad Jump station, where athletes must jump forward after each burpee for 80 m. The vertical power and hip flexor strength from tuck jumps directly transfer to longer broad jump distances. They also improve running speed by training fast-twitch fibers and reactive strength. Program 3-4 sets of 5-8 reps as part of a plyometric warm-up, 1-2 times per week. Always perform after a thorough warm-up and before strength or running work.

Variations & Alternatives

• Skater Jump - lateral plyometric for frontal-plane power and hip stability
• Single Leg Hop - unilateral plyometric for running-specific reactive strength
• Wall Ball Thruster - loaded explosive movement combining squat and overhead press

FAQ

Are tuck jumps safe for beginners? Tuck jumps are an advanced plyometric. Beginners should master squat jumps and broad jumps first, then progress to tuck jumps once they can perform 10+ controlled squat jumps with soft landings.

How do tuck jumps improve broad jump distance? Tuck jumps develop the explosive hip and knee extension needed for takeoff, along with the hip flexor power that drives the knees forward during the flight phase. Both contribute to longer broad jump distances.
