How many reps of the groiner lunge should a beginner do as a warm-up?

Do 5 to 8 unhurried reps per side as part of your warm-up before squats, lunges, or sprint work, holding each stretched position for a breath or two. It's a mobility prep drill, not a strength exercise, so there's no need to add sets or chase more reps as you improve; let the range grow naturally on its own.

What's an easier or harder version of the groiner lunge?

To make it easier, step the front foot only partway out instead of all the way beside the hand, keeping the stretch shallow. To make it harder, walk the back foot farther away before you start, or add a rotation by reaching the same-side arm toward the ceiling once you're settled in the stretch.

Who is the groiner lunge good for, and when should it be skipped?

It's a dynamic warm-up for the adductors and hip flexors that primes the groin before squatting, sprinting, or lateral movement, not a strength or conditioning exercise on its own. Skip it if you have an irritated groin or hip flexor, since the deep stretched position can aggravate a strain that needs rest instead of range of motion.

Beginner

Groiner Lunge

The groiner is a staple dynamic warm-up that mobilizes the adductors and hip flexors by sinking into a deep lunge and pulsing the hips. It prepares the groin for sprinting, lateral work, and heavy squatting without the sedative effect of long static holds. Keep it rhythmic and controlled to prime the inner thigh for work.

How to do it

1
Start in a push-up position with hands under your shoulders.
2
Step or hop one foot up to the outside of the same-side hand.
3
Keep your back leg long and press your hips down toward the floor.
4
Feel the stretch along the inner thigh and front of the hip, holding a moment.
5
Return the foot to the start under control.
6
Alternate sides for smooth, rhythmic reps.

Tips

Drive your hips down and forward rather than just planting the foot.
Keep the back leg actively straight to deepen the hip-flexor and adductor stretch.
Use it as a warm-up; move with control and do not bounce aggressively.

Variations

Common mistakes

The front foot lands flat next to the hand instead of stepping outside it, pinching the hip instead of opening the groin.
The hands walk backward toward the front foot to make the position feel easier, shortening the stride and shrinking the stretch it's meant to create.
The torso twists to look down at the front knee instead of staying square, adding an unwanted rotation through the lower back.
The front shin drifts forward past the toes as the hips sink, shifting your weight forward onto the front foot instead of opening the groin and hip flexor.
Rushing through both sides without holding the position at all skips the one moment where the stretch actually does anything.
