Frog

Frog Exercise Description

Frog is a body-weight plyometric that combines a deep squat with a forward jump, emphasizing explosive triple extension at the hips, knees, and ankles. It primarily targets the gluteus maximus, quadriceps, and calves, with the hamstrings and core assisting in control and trunk stability. Performed rhythmically over distance or time, it can elevate heart rate while training powerful takeoffs and controlled, soft landings. The key to safe, effective execution is maintaining a neutral spine, keeping the chest up, and aligning knees to track in line with the toes during both takeoff and landing. Use a clear, non-slip surface and focus on absorbing impact by flexing through the hips, knees, and ankles as you land.

How To Do The Frog Exercise

‘- Stand athletic: feet shoulder-width to slightly wider, toes turned slightly out, chest up, eyes forward, arms at sides.
– Brace lightly through the midsection; set shoulders down and back without flaring the ribs.
– Hinge the hips back, then descend into a deep squat as mobility allows, keeping heels in contact and spine neutral.
– Swing the arms back to load; keep knees tracking over the toes (avoid inward collapse).
– Drive explosively through the feet, extending hips, knees, and ankles while swinging the arms forward to jump slightly forward.
– In the air, stay tall and aligned (no excessive arching or folding).
– Land softly on the midfoot and allow the heels to settle; immediately flex the hips, knees, and ankles to absorb force.
– Finish the landing in a controlled squat with the chest up and knees aligned over the toes.
– Reset posture if needed, then repeat with the same distance and controlled rhythm.
– Stop the set if you cannot maintain quiet, controlled landings or neutral spine.

Frog Tips

‘- Set up with feet shoulder-width to slightly wider, toes turned slightly out, chest up, and eyes forward.
– Lightly brace your midsection and draw the shoulders down and back without flaring the ribs.
– Hinge your hips back first, then sink into a deep squat as mobility allows while keeping your heels in contact and spine neutral.
– Keep your knees tracking in line with your toes during the squat and avoid letting them collapse inward.
– Swing your arms back to load, then drive explosively through your feet, extending hips, knees, and ankles as you swing the arms forward.
– Stay tall and aligned in the air, avoiding excessive arching or folding at the hips.
– Aim to jump slightly forward each rep, maintaining a consistent distance and controlled rhythm.
– Land softly on the midfoot, then allow the heels to settle while immediately flexing hips, knees, and ankles to absorb impact.
– Finish each landing in a controlled squat with the chest up and knees aligned over the toes.
– Use a clear, non-slip surface and stop the set if you can’t maintain neutral spine or quiet, controlled landings.

Frog Beginner Introduction

Frog is a dynamic, body-weight power move that blends a low squat position with a forward hop. It relies on a strong push through the hips, knees, and ankles, so the glutes, thighs, and calves handle most of the effort, while the hamstrings and core support balance and control. Because it is usually repeated for distance or time, it naturally raises the heart rate and feels similar to a short burst of athletic conditioning work.

The movement centers on an upright, organized posture, steady alignment through the legs, and smooth, cushioned landings. The torso stays stable while the legs cycle between a deep bend and a strong drive off the floor. A firm, stable surface and rhythmic arm swing contribute to a fluid pattern, helping each jump flow into the next. With consistent practice, this drill reinforces powerful takeoffs, better body awareness in a low squat, and gentle, controlled contacts with the ground.
