Power Loss Thresholds Instead of Rep Counts

[krasney]

In velocity-based training, lifters often set velocity-loss thresholds instead of defining a fixed number of reps. So, rather than saying "I want to do X sets," the lifter can say "I want to lift until I lose 20% speed—then alert me and I'm done."

Echo mode is amazing because you can just define the speed you want to lift at, rather than the specific weight. It would be cool if, instead of setting a fixed number of reps, we could define a desired power loss (force * velocity) over the last concentric rep vs the max concentric rep. If I said "I want to lift until I lose 20% power," the Vitruvian could automatically end the set once I've hit the power loss threshold. This would reduce the rate of injury, maximize efficacy of each lift, and further demystify how many reps you should do given your level of fatigue that day/set/rep.
