BOSU Straddle Jump

Target muscles

The quads, glutes and calves generate the explosive triple-extension that launches each jump, then absorb the landing eccentrically. The core stabilises mid-air and on touchdown, and the constant in-and-out footwork over the dome sharpens the small stabilisers that protect the ankles and knees during reactive movement.

How to perform

Setup

Stand with the BOSU dome between your feet, one foot planted on each side of the dome on the floor. Soften the knees and set a tall, athletic posture.

Execution

Dip into a quarter-squat and jump up, bringing both feet onto the top of the dome or together over it, then immediately jump back out to the straddle stance. Land softly each time — toes first, knees bending to absorb force, hips back. Keep a steady rhythm and stay light on your feet. The aim is quick, controlled ground contacts, not maximum height.

Common mistakes

• Landing stiff-legged with locked knees, which sends impact straight into the joints.
• Letting the knees collapse inward on landing.
• Looking down at the dome instead of keeping the chest up and eyes forward.
• Going so fast that landings become sloppy and balance is lost.

Progressions and regressions

Regress to stepping in and out over the dome, or to straddle hops without the BOSU, to build the pattern and confidence. Progress by increasing speed, adding height, or holding the count for timed intervals. A single-leg version dramatically raises the balance and power demand.

Programming notes

Program it as plyometric conditioning, 3-4 sets of 20-40 seconds or 10-15 contacts, with full rest if power is the goal and shorter rest for conditioning. Place it early in a session when the legs are fresh if you want quality jumps. Skip it if knees or ankles are irritated — reactive jumping on an unstable surface is demanding on the joints.
