Why You Keep Getting “Under” in Pole Vault (And How to Fix It)

April 27, 2026 by TFVision

You’re putting in the hours, hitting the runway hard, but your vaults keep ending with you “under” the bar instead of clearing it. You feel like you’re close, but something’s just not clicking at takeoff. Sound familiar? If you find yourself “under” the bar repeatedly, it’s a common struggle—and it’s something you can fix.

Why This Problem Happens

Getting “under” the bar in pole vault usually means you’re not finishing your takeoff or swing properly. Instead of transferring your run-up speed and energy upward and forward, the pole bends but doesn’t launch you over the bar. You end up stuck below the bar, sometimes even knocking it off with your body.

This happens because the body position, timing, or pole placement during takeoff isn’t syncing. With a poor angle or a late swing, you lose the power needed to rise. Since pole vault combines speed, strength, and technique, even small technical faults can throw off the whole vault.

What Good Technique Looks Like

A good vault starts with a strong, controlled plant of the pole at takeoff. You want your body to move up and away from the runway—almost like you’re pushing off a springboard. At the moment of takeoff:

Stay tall and avoid collapsing forward.
Drive your lead knee up to start the swing early.
Keep your arms extended and finish the swing quickly.
Transfer forward momentum into vertical lift by pushing into the pole and pulling your hips upward.
Focus on clearing the bar with your chest and hips in line, not dropping your head or shoulders early.

Good technique feels like a smooth, explosive movement from sprint to swing, finishing with an active, committed push into the pole.

Common Mistakes

Rushing the takeoff and missing the pole plant timing.
Dropping the chest or head forward too soon—losing upward drive.
Not finishing the swing, leaving your legs behind.
Bending too much at the waist, causing you to “collapse” under the bar.
Holding the pole too far forward or too low, limiting energy transfer.
Running fast but not converting that speed into a clean takeoff.

How to Fix It (Coaching Solutions)

Use These Cues

“Stay tall at takeoff” — keep your posture strong.
“Drive the knee up early” — start the swing quickly.
“Finish the swing—don’t leave your legs hanging.”
“Extend your arms and push into the pole.”
“Don’t rush the plant—wait for the right pole placement.”

Drills to Try

Pole plant drills: Practice planting the pole at the right spot with a slow approach.
Swing-through drills: Use a rope or light pole to work on a full and active swinging motion.
Takeoff posture drills: Jump off one foot, focusing on staying tall and driving the knee up.
Short approach vaults: Reduce your approach speed to focus on technique.

Adjustments to Make

Slow down your approach if your plant and takeoff feel rushed.
Check your grip height and pole carry for better control.
Focus on body position during the swing—practice in front of a mirror or video.

How to Use TFVision

For Athletes Training Alone

When you’re training solo, filming your vaults is key:

How to film: Set your camera to capture the entire vault from the side to see takeoff, swing, and bar clearance.
What to look for: Watch your body position at takeoff—are you staying tall? Are you finishing your swing? Is your pole plant consistent?
How to self-correct: Use TFVision to slow down your videos, mark areas where you lose posture or don’t finish the swing, and compare your attempts over time to see progress.

For Coaches

Coaches can use TFVision to:

Review athlete videos efficiently: Spot consistent technical misses like a poor takeoff or incomplete swing.
Give clearer feedback: Use clips to show exactly where the athlete needs to improve, reinforcing coaching cues with visual proof.
Track progress: Save videos throughout the season and compare vaults to monitor improvements in technique and bar clearance.

Weekly Training Integration Example

Day 1: Record a vault attempt, upload to TFVision, and analyze technique focusing on takeoff and swing.
Day 2: Drill corrections based on feedback (e.g., pole plant or swing drills).
Day 3: Re-test with new vault attempts and compare side-by-side videos in TFVision.

In-Season vs Off-Season Use

In-Season: Keep feedback light and focused on maintaining rhythm and small technical tweaks. Avoid overloading athletes with too much video analysis during competition weeks.
Off-Season: Deep dive into technique, breaking down every part of the vault using video to make bigger improvements.

Real-World Scenario

Imagine an athlete consistently getting “under” at takeoff. During video review with TFVision, the coach spots that the athlete's chest dips forward too early and the swing doesn’t finish fully. Using the tool, the athlete watches slow-motion clips of their attempts, recognizing the issues themselves.

With targeted cues and drills to “stay tall” and “finish the swing,” the athlete works on these areas in practice. Over the next week, filming each attempt with TFVision helps track small but important improvements. Eventually, the athlete clears higher bars by converting more run-up speed into upward momentum.

Benefits of Using TFVision
