Go From Guessing to Coaching Yourself With Biomechanical Feedback

If you’re reading this, you are probably someone who tracks their reps, sets, weights, times, and anything else you can think of in training. But the clock, barbell, and RPE only tell one part of the story.

If you care about real performance, that kind of tracking is incomplete.

Because the clock and the barbell only tell you what you did.

They don’t tell you:

• How you moved.
• If your positions started breaking down in round 3.
• If your range of motion shortened.
• If your rep speed fell off 30% in set two, though the weight didn’t change.

And those details matter. A lot.

Two athletes can do the very same workout and get similar or the same time — but have a very different stimulus. One athlete may have been working under their capacity, moving well, and maybe even increasing speed as they came closer to completing the workout. The other athlete may have redlined from the start, working at full capacity. Their movement quality might have broken down as they went. And they might have been using extra energy compensating in the movements they aren’t as efficient in.

If we just looked at their times, there would be no way of telling that one athlete had a far worse performance qualitatively than the other.

With WurQ, these unseen details are revealed. Having visibility into how your body is actually moving allows you to make better decisions in your training.

What Does WurQ Do?

WurQ uses a dual-sensor system — one on the wrist, one on the chest — to track your movement in 3D space as you train. These are biomechanical sensors trained via deep learning models at the Harvard Motion Capture Lab and validated through the NFL Players Health Study, not just a fitness tracker watch. 

This biomechanical data, with lab-level accuracy, was built to directly inform training decisions.

It automatically detects and logs over 100 movements common in CrossFit: Olympic lifts, gymnastics, metcon staples. And it gives you:

• Movement efficiency: through analysis of the distance traveled—were your reps consistent in depth, extension, and control, or did they break down?
• Stamina: through rep cycle duration (how long each rep takes) and the amount of rest vs. active time, and how that changes over time based on different WOD durations, weights, etc.
• Effort: based on how hard your heart worked and which movement spiked it the most—where you can push and where to slow down to keep your engine running at a consistent rate.
• And finally, Workload: visualizing your total volume to help optimize training, avoid injuries, and maintain safe and consistent gains weekly.

You just train, and WurQ captures how you're moving, not just what you're doing.

How Does It Inform Training Decisions?

Data is only useful if it leads to decisions.

Let’s say your overhead pressing is plateauing. You’re training consistently, loading appropriately, eating right, and recovering well. But you can’t seem to add weight to the bar.

So, let’s say you’re doing 5x5 @ 80% of your 1RM. You look at your WurQ data and see this: by set 3, your ROM shortens by 15%, and your rep speed (power) drops by 25%. You're moving the weight, but your movement quality is falling off. On paper, you have "successfully" completed your 5x5 overhead press — but you're not maximizing the full pattern across all five sets. You're compromising your movement to get the work done.

This data allows you to start asking yourself:

• Do you lower volume and chase higher-quality output?
• Do you adjust rest to sustain ROM across sets?
• Do you reduce intensity slightly to maintain full ROM under fatigue?

Data allows you to go from guessing to coaching yourself without waiting weeks to see if what you’re doing is working.
Without WurQ, you don’t even know the problem exists.

And that’s just one example. WurQ surfaces patterns you’d never catch with a clock or a logbook:

• Pull-up ROM falling off halfway through metcons
• Intra-metcon rest intervals creeping longer than intended
• Asymmetries showing up under fatigue
• Power output dropping on repeat efforts, even when time stays the same

Data Isn’t Just for Elite Athletes

You don’t need to be a Games athlete to benefit from data.

Training hard only works if you're reinforcing the right patterns. Without visibility, you might be putting in effort that never compounds.

If you care about moving better and maximizing every training session, WurQ gives you the data to do that. It’s not about complexity. It’s about visibility.

Biomechanical feedback gives you the tools to work hard on the right things.

You can’t improve what you can’t see.
