Plant.
Invert.
Fly.
The plant is the moment that converts horizontal speed into vertical lift. From the four-count rhythm at the back of the runway to the upside-down stack over a bent fiberglass pole, this is the geometry of going up.
From box to bar.
A pole vault is six phases in roughly two seconds. The plant is phase five, the moment the pole tip strikes the back of the box and the energy of the runway flips upward. Everything before is acceleration; everything after is the inverted swing. The numbers below are general guidelines: HS boys typically clear 8 to 13 ft (2.44 to 3.96 m), advanced HS boys 14 to 16 ft (4.27 to 4.88 m), and elite HS boys 17 ft+ (5.18 m+). HS girls clear 7 to 11 ft (2.13 to 3.35 m), advanced HS girls 12 to 13 ft (3.66 to 3.96 m), and elite HS girls 14 ft+ (4.27 m+). The range varies enormously by program quality and gymnastics background.
◆ Data Check: Why the Plant Decides the Vault
An athlete cannot vault what they cannot generate. The pole stores only the kinetic energy delivered at takeoff. A tenth of a foot per second lost in the last two strides costs roughly three to four inches of bar height. The plant is where speed becomes height, but only if the top hand is stacked, the takeoff foot lands under the grip, and the pole tip arrives at the back of the box before the foot leaves the ground.
The vault is decided in the run, not the air. A tall, fast, accurate run wins; a beautiful invert on a bad run does not. Cue it as a tall run: eyes up, hips tall, pole quiet through the drive and transition zones, top arm firing in the plant zone.
◆ Three Zones of the Approach
Drive zone (first 4 to 6 strides): accelerating with the pole carried high, body upright, building speed. Cue: tall run, eyes up, pole quiet.
Transition zone (middle strides): lowering the pole tip toward the box, building to top speed, maintaining posture. Cue: tip drops, speed builds, posture stays tall.
Plant zone (last 2 to 3 strides): top arm drives up, pole tip drops into the box, takeoff foot strikes directly under the grip. Cue: stack the top hand, plant tall.
| Phase | Trigger | Duration | Top Hand | Pole Tip | Result |
|---|---|---|---|---|---|
| 01 / Run | Start mark | ~3.5 s | Carries pole | Forward, low | Build speed |
| 02 / Pre-Plant | 2 strides out | ~0.5 s | Drives upward | Tracks toward box | Tip aimed |
| 03 / Plant | Last stride | ~0.2 s | Stacks above head | Strikes box back | Energy locked |
| 04 / Takeoff | Foot leaves | ~0.0 s | Pressing, stacked | Pole loads | Vertical drive |
| 05 / Swing | Trail leg | ~0.4 s | Pulls and locks | Bending | Inverted pendulum |
| 06 / Invert | Hips above shoulders | ~0.2 s | Pushes off | Recoiling | Vertical-inverted |
Down, up, out, plant.
The last four strides are choreographed as a count-down. Each call cues a hand position and a pole-tip target. Rhythm wins over force; the pole has to arrive at the box, not be thrown there. These counts are general progressions: beginning vaulters often start with a simplified two-count (down, plant); developing and advanced vaulters build toward the full four-count as their pole-carry posture and runway accuracy improve.
◆ Reading the Diagram
The four count cards below run from left (stride minus 4) to right (takeoff). The pole tip position and the top-hand path are the two things to track: the tip must be tracking toward the box before the plant zone begins, and the top hand must be fully stacked overhead before the foot leaves the ground. Swing long: the longer the swing after takeoff, the more energy goes into the pole. Invert late: trying to invert before the swing is finished stops the bend and pops the athlete off the pole before peak energy return.
The numbers are general guidelines, not exact targets. Beginning vaulters plant with a shorter grip and a lower top-hand position. Advanced vaulters reach full extension with the top hand stacked directly over the takeoff foot, or up to a hand-width behind it. Never in front.
Pole tip drops
Tip lowers from carry to belt height. Bottom arm stays relaxed, top arm prepares to fire. Posture stays tall, no leaning into the pole.
Top hand drives
Top arm starts the upward path. Tip rises slightly, then begins tracking toward the box. Eyes on the back of the box, not the bar.
Pole extends
Top hand passes the helmet line. Pole rolls over the shoulder. Bottom hand releases pressure, becomes a guide rather than a brake.
Tip strikes box
Top arm fully stacked above the head, takeoff foot lands directly under the top hand. Tip hits the back of the box; foot leaves the ground a beat later.
Foot under top hand.
A free takeoff means the foot is directly below or slightly behind the grip. Reach the foot in front of the grip and the pole brakes; pull it too far back and the vault stalls. These distances are the ranges that make a free takeoff repeatable for HS varsity. Approach speed at takeoff for HS boys runs 22 to 27 ft/s (6.7 to 8.2 m/s); elite men reach 30 to 33 ft/s (9.1 to 10.0 m/s). Pole bend at peak runs 50 to 70 degrees for HS boys; elite men exceed 80 degrees on a properly sized pole.
◆ Tall Run = Big Vault: The Speed Math
Vault height comes from kinetic energy at the plant: KE = 1/2 x m x v squared. Doubling the speed roughly quadruples the energy stored in the pole. A quick comparison for an average HS boy on a properly sized pole:
22 ft/s (6.7 m/s) approach stores energy for roughly 11 ft (3.35 m) clearance. 25 ft/s (7.6 m/s) stores energy for roughly 13 ft (3.96 m). That is nearly a 30 percent jump in stored energy from a 14 percent speed increase. 28 ft/s (8.5 m/s) stores energy for roughly 15 ft (4.57 m).
Approach speed is the king variable. Acrobatics off the top of the pole add inches at most; the run adds feet. A beautiful invert on a slow run does not move the bar up. A tall, fast, accurate run on a slightly imperfect invert still clears.
◆ Four Mistakes To Avoid: Under-Run, Low Plant, Early Invert, Bail Plant
A vault breaks in four recognizable ways once the run stops working. Under-Running the Plant: deceleration in the last 4 strides, approach speed dies, the pole barely bends, and upper-body strength cannot save it. The Low Plant: the top arm never fully extends overhead, the athlete hangs from a shallow angle, and the pole builds no bend. The Early Invert: the athlete tries to invert before the swing finishes, killing the pendulum and popping off the pole before peak energy return. The Bail Plant: the athlete senses a bad approach and plants without committing, ending up under the bar.
Fix them with timed short-approach pole runs (catch deceleration on a stopwatch), wall plants for full overhead extension, rope or ring swings for the long pendulum before the knee tuck, and pop-up vaults from a 4-stride approach to train commitment. The cue: a tall, fast, accurate run is the whole vault. The air is just where the energy goes.

The pole, loaded.
Bend angle is a stand-in for stored energy. From plant to peak, the pole loads in roughly six tenths of a second; from peak to release, it recoils about as fast. Elite vaulters reach 80 degrees of bend at peak; HS varsity tops out near 50 to 70 degrees on poles rated for their weight. These are general guidelines: a vaulter on an undersized pole will over-bend; a vaulter on an oversized pole will under-bend and lose energy return. Pole selection is part of the performance equation.
◆ Sources & Method: Representative Triangulation
This curve is a representative model triangulated from three sources, not a single measured dataset reproduced here. The shape (plant near zero, peak bend around 0.5 to 0.6 s, return toward straight near release) and the peak values (elite ~80°, HS varsity ~50 to 70°) follow the literature; the intermediate points are illustrative. Read the originals to go deeper.

Upside down, on purpose.
Full invert means hips pass the shoulders and the body is vertical-inverted relative to the pole. It is the position that converts swing momentum into the push-off. The percentage of vaulters who consistently reach it climbs steeply with experience; below it, height is left in the box. Inversion is not a deliberate action applied to the top of the swing: it is the natural endpoint of a long, committed swing. Swing long; invert late. Trying to invert early stops the swing and wastes energy. These bar charts are general guidelines based on experience level, not fixed standards.
Six, eight, or ten.
Approach length is a function of top-end speed, pole length, and grip height. Longer is not always better; it has to be runnable in rhythm. HS boys typically run an 8-step from a 108 ft to 118 ft mark (33 to 36 m); elite men cover 16 to 18 strides from 138 ft to 151 ft (42 to 46 m). The PR ranges in the table below are general guidelines based on grip height and approach speed. Beginning vaulters stay at the shorter approach until accuracy and rhythm are locked; developing and advanced vaulters extend the approach as speed and grip height increase together.
| Approach | Total Distance | Top Speed | Grip Height | Typical PR Range | Best For |
|---|---|---|---|---|---|
| 6-Step | ~78 ft(24 m) · 12 strides | ~21.3 ft/s(6.5 m/s) drill | 10 ft 6 in(3.20 m) | 8 ft 2 in to 10 ft 6 in(2.50 to 3.20 m) | Beginners · Drills |
| 8-Step | ~112 ft(34 m) · HS standard | ~24.6 ft/s(7.5 m/s) repeatable | 12 ft 10 in(3.90 m) | 10 ft 6 in to 14 ft 1 in(3.20 to 4.30 m) | HS Boys · HS Girls |
| 10-Step | ~125 ft(38 m) · advanced HS | ~26.9 ft/s(8.2 m/s) controlled | 13 ft 9 in(4.20 m) | 13 ft 9 in to 15 ft 9 in(4.20 to 4.80 m) | HS Elite · College |
| 16+ Step | 138 to 151 ft(42 to 46 m) | 29.5 to 31.2 ft/s(9.0 to 9.5 m/s) elite | 15 ft 9 in to 17 ft 1 in(4.80 to 5.20 m) | 18 ft to 20 ft 4 in(5.50 to 6.20 m) | Elite Men |
Train the run, own the vault.
You cannot fix a bad plant by adding more inversions in the pit. The nervous system has to feel the tall run, the stacked plant, and the long swing before it can produce them at race speed. These drills isolate each element. They are general progressions: scale the approach length and grip height to the athlete in front of you.
Pole Runs (No Vault)
Full or short approach with the pole carried, no plant, no vault. The entire focus is on running tall with the pole quiet: eyes up, hips tall, pole carried in a high position through the drive zone. Hit the takeoff mark consistently before adding the plant. This drill reveals accuracy problems before they cost misses in the pit.
Wall Plant Drill
Stand 6 ft from a wall, drive the top arm fully overhead, and plant the pole tip into the wall while the top hand stacks above the head. The wall gives instant feedback: if the top hand is not high enough, the athlete feels it in the grip angle. Builds the motor pattern of full extension before the pattern has to happen at runway speed.
Pop-Ups (4-Stride Approach)
Short approach, plant, takeoff, ride the pole up to vertical, drop into the pit. No bar, no inversion pressure. The entire focus is on the takeoff position and letting the pole come up rather than forcing it. Pop-ups on a short approach generate enough energy to feel the swing without the complexity of a full approach. Add the bar only after takeoff posture is consistent.
Swing Drills (Rope or Rings)
Hanging swing on a rope or gymnastics rings, full body extension on the swing-up. The drill teaches the long swing: body extends on the way through the bottom, then the knees come through last. Athletes who try to invert early will feel the difference immediately. The feeling of the long swing off rings transfers directly to the swing phase on the pole.
◆ Conditioning Note: Vault Sessions Are Short by Design
Vault sessions top out at 12 to 20 vaults for most HS athletes. Fatigue destroys plant accuracy; more reps past that threshold practice bad technique, not good technique. For conditioning, supplement with bodyweight gymnastics: handstands, bar swings, pull-ups, hanging leg raises, and rope climbs.
The strongest predictor of HS vaulters who eventually reach 14 ft+ is gymnastic-style upper body strength combined with sprinter speed. If an athlete can hold a handstand for 5 seconds, do 10 pull-ups, and run a 4.6 to 4.7 second 40-yard dash, they have the physical foundation. Everything else is technique and pole selection.
