Slow Is the Work
Why slowing a movement down makes it harder, and better.
The instinct is to speed up. More reps, more pace, more proof you're working. On the reformer, the opposite is true.
Slow is the work. When you take the tempo down - really down, slower than feels natural - there's nowhere to hide. No momentum to borrow. The muscle has to do the thing the whole way through, on the way out and on the way back. That second half, the return, is where most people give the weight away. Slow it down and you keep it.
Three things to try in your next class:
Count the return. However long it takes you to press out, take twice as long coming back. The eccentric - the lengthening - is half the movement and the half most often thrown away.
Find the stop. At the end of a range, pause. No bounce, no rush into the next rep. The pause is where control lives, and control is the whole point.
Drop the count, keep the tension. Fewer reps, fully felt, beats a fast dozen. If you can talk through it, you're moving too fast.
None of this is about doing more. It's about giving less away. The carriage will tell you the truth - let it move slowly enough to hear it.
