  • Live PR badges
  • Muscle engagement

Gravitus Pro tools

The numbers you need, one tap from the set.

Every exercise carries a tool bar while you lift. No leaving the workout, no second app, no mental math between sets.

PLATES tool: the bar drawn with 45, 25 and 5 pound plates per side for 195 pounds
Plates draws the bar for the weight you're about to load, per side.
STRAIN tool: an effort score for the set on a zone bar from warmup to heavy
Strain scores the effort of the set you're about to do against your max.
MAX tool right after a PR set: 292 pounds, new max today, up 6, with rep maxes from 1 to 10
Max updates your 1 to 10 rep maxes the moment a set lands.
TREND tool: a verdict on whether the lift is climbing, with the recent trajectory
Trend tells you whether the lift is actually moving, and by how much.
