Time under tension, now measured.

Not all reps are created equal. Stop letting soft ones slip in. Instead count time under tension, not reps.

Your body doesn't feel reps, it feels fatigue created by seconds and pounds (or kilograms for our friends not in the US).

tensr.fitness now lets you log the mechanical work your muscles actually did, using tensr.fitness. You need a Bluetooth sensor, and then connect to the app, and you can record the force-time curve of every set, and shows you whether today’s session was harder, softer, or the same as last week.

How it works

1. Bring a sensor. A Tindeq Progressor, a Weiheng WH-C06, or even a KForce-Link, or many other BLE sensors supoprted soon.
2. Clip In Add the sensor in-between your anchor and your handle using any of: stright bands, loops, cable mahcine, TRX, gym rings, etc.
3. Train. Open the tensr app in Chrome (or Edge), pair the sensor, hit start.
   No accounts, no install, cloud optional. Seriously.
4. See the data. Time under tension, impulse, peak force, and a session-over-session view that tells you if you actually progressed. All local. All exportable. Yours.

What tensr is for

• The data-geek home-gym lifter. You already train hard. You want a number, not a guess.
• Remote coaches and physical therapists. Band programs you prescribe, with objective evidence the work happened at the prescribed intensity.

We’re building in public. Infrequent updates — a new sensor supported, a significant feature landing, the Cooper Clinic pilot opening. Nothing else.
