Super slow training and the 10/10 protocol: maximum time under tension, minimum joint cost
Super slow training. Ten seconds up, ten seconds down. Keeps the muscle under tension in the hypertrophy zone while collapsing joint forces. The safest, hardest way to lift.
Most lifting injuries don't come from being weak. They come from being fast. Momentum loads joints with forces no muscle ever asked for. And the body pays the bill years later.
What slow cadence actually means
On every rep: a 10-second concentric (lift), a 10-second eccentric (lower). No pause to recover, no bounce off the bottom, no jerk through the sticking point. The weight should look like it's moving through honey.
Three things that disappear instantly
- Momentum. The muscle, not your kinetic energy, has to move the weight.
- Joint impact. Peak forces drop dramatically; chronic injuries fade.
- The ability to cheat. There's no rep you can fake to ‘count’ it.
Why it feels so much harder
Because it is. A weight you can curl twelve times conventionally might give you four honest reps at 10/10. That isn't a deficiency. It's the first time you've actually lifted the weight with only the muscle. Your previous reps were assisted by physics.
Slow cadence turns a moderate weight into a brutal stimulus. It's how a 50-year-old can train as intensely as a 20-year-old without ever risking their joints.
How Intensiq guides you
The app vocally counts every second of the up-phase and down-phase. You don't have to think. You just have to keep the bar moving exactly when the coach says. Most users find their first slow set the hardest workout of their year.
