Sprint Start — from Prone

Quick Intro

Sprint Start — from Prone is a start drill performed lying face down, popping up and accelerating explosively into a sprint the instant the start signal fires.

Equipment Needed

No equipment is strictly needed for Sprint Start — from Prone beyond a partner or coach delivering the start signal at an unpredictable moment, the same as in any reactive sprint start.

Why Sprint Start — from Prone Matters

Starting flat on the ground adds a whole extra phase the standing versions don’t need: getting the body from the floor to a sprinting posture before acceleration can even begin. Driving the hands into the ground to pop the hips up first, then getting the feet under the body fast, is what determines whether that transition wastes the reactive advantage of a fast signal read or preserves it. The glutes (gluteus maximus), outer quad (vastus lateralis), hamstrings (biceps femoris), calves (gastrocnemius) and hip flexors (iliopsoas) drive the pop-up and the explosive steps that follow, while the chest (pectoralis major) and triceps brachii drive the hands-into-the-ground push that starts the whole sequence. Reaction time is the main demand, with coordination next and speed and power close behind, since the signal has to be answered with a push off the floor, a pop to the feet and a sprint. Compared with Neuromuscular Sprint Start, more of the body is involved, because the floor-to-feet transition comes before the first step.

When to Do It

This carries an explosive cost on top of a floor-to-feet transition, so it fits best early in a session while the legs are fresh, with generous recovery between reps.

Anyone with a current hamstring, hip flexor, shoulder or wrist issue that limits an explosive floor pop-up should wait until it heals. Neuromuscular Sprint Start’s standing-or-crouched version is the more natural starting point for anyone new to reactive sprint starts.

Getting Ready

A few submaximal pop-ups from prone, without a reactive signal, confirm the transition from the floor to a sprinting posture feels solid before the true reactive version begins.

Step-by-Step Instructions

Lie face down on the ground, hands positioned near the chest, ready to push.

React the instant the signal fires, driving the hands into the ground to pop the hips up first.

Get the feet under the body as fast as possible and drive immediately into the first explosive steps of the sprint.

How Many, How Often

Sprint Start — from Prone is dosed by clean reactive starts per set, not total distance, since a fast, efficient floor-to-sprint transition is the skill being trained.

Level	Where you’re at	What to do
Beginner	Learning the floor-to-feet transition	3 sets of 3 to 4 starts, accelerating 10 metres each time, with full recovery between reps.
Intermediate	The pop-up feels quick and the sprint follows cleanly	3 to 4 sets of 4 to 5 starts, accelerating 10 to 15 metres each time.
Advanced	The transition and acceleration both feel sharp	4 sets of 5 to 6 starts, with the signal timing varied unpredictably.

Full recovery between reps matters more here than squeezing in extra starts, since a fatigued pop-up wastes the reactive advantage this drill is built around before the sprint even begins.

Modifications and Variations

This exercise has one direct relative: Neuromuscular Sprint Start, the standing-or-crouched version this drill adds a floor-to-feet transition on top of.

Progression path: Sprint Start — from Standing grooves the basic reactive start first, Neuromuscular Sprint Start builds the standard version, then Sprint Start — from Prone and Sprint Start — from Various Positions (random) each raise the difficulty from there.

Common Mistakes to Avoid

Rising to the knees before driving toward the feet. Pausing in a half-up kneeling position wastes time that a direct hands-to-feet transition would have saved. Popping the hips up and getting the feet under the body in one continuous motion is what preserves the reactive advantage.

Standing up too tall before the first few steps. Popping the torso vertical before the third or fourth step kills the forward lean driving acceleration, the same fault every sprint start is prone to. Keeping the first steps short, powerful and low is what sets up everything that follows.

After Your Set

The hamstrings, hip flexors, chest and triceps take on a heavy load through a set of these. A standing hamstring stretch and a doorway chest stretch settle things afterward.

Going Deeper

This belongs early in a session, while the legs, shoulders and nervous system are all fresh, since a fatigued pop-up and a fatigued first step compound each other and both get slower together.

Progress here comes down to how efficient the floor-to-feet transition itself becomes, not how fast the sprint looks once it’s underway. Someone who’s sprinting well after a slow, fumbled pop-up hasn’t mastered the skill this version specifically trains, even if the overall time looks decent. Once the transition happens in one clean, continuous motion, the reactive advantage of a fast signal read finally carries all the way through to the sprint.

Most people need many sessions before that floor-to-feet transition stops feeling like a separate, effortful step.

How to Know You’re Improving

The pop-up happens in one continuous motion, without pausing on the knees
The transition from floor to first step keeps getting quicker

A faster, cleaner floor-to-feet transition is a better sign of progress here than the sprint speed that follows it.

Muscles Worked

Gluteus Maximus (the largest glute muscle, driving the hips up off the floor and into the run)
Vastus Lateralis (a front thigh muscle on the outer side, extending the knee as the body rises)
Biceps Femoris (a muscle at the back of the thigh, pulling the leg under the body on the first stride)
Gastrocnemius (a calf muscle, making the first contact once the feet are under the hips)
Iliopsoas (the hip flexor group at the front of the hip, drawing the knee up out of the lying position)
Pectoralis Major (the chest muscle, pushing the torso off the ground to start the rise)
Triceps Brachii (the back of the upper arm, straightening the arms to lift the body clear)

FAQ

Why does starting from prone add difficulty over the standing version? Lying face down adds a whole extra phase, getting from the floor to a sprinting posture, that the standing version doesn’t need, and any hesitation there wastes the reactive advantage of a fast signal read (see Why It Matters above).

What’s the main technical fault in the pop-up itself? Pausing on the knees on the way up, which wastes time a direct hands-to-feet transition would have saved. Popping the hips and getting the feet under the body in one motion is the fix (see Common Mistakes to Avoid above).

Is this a good starting point for reactive sprint starts? No. Neuromuscular Sprint Start’s standing-or-crouched version is the more natural entry point, with this version reserved for once that base reactive start already feels reliable.
