Reverse-band deadlifts with a brake.

The reverse band makes the weight lighter at the bottom. We also add a magnet brake on the bar. The brake almost cancels out the bands.
What this does is make the weight at the very start the same as though there were no bands. Once you break the brake, you get the band benefit.
We do it to train speed off the floor. It’s a hassle to set up but it’s effective.
