Setrung
A training log that tells you what to do next session
Log your sets in the gym. Setrung works out the weight and reps to go for next time, and shows whether you are getting stronger and which muscles need more work.
Free. Works in the browser on any phone or computer.
What it does
One tap per set
The workout starts filled in from last time. Log the next set with one tap. It saves to your phone first and syncs when there is signal, so a weak connection in the gym does not lose a set.
What to do next session
Each exercise gets a suggestion by double progression: hit your reps and it adds weight, miss and it asks you to beat last time's reps. It says when a lift has stalled or is slipping, and why.
Strength trend
Each session's best set becomes an estimated one-rep max, so different weights and reps compare. You see the change overall and per muscle group, and it says when a change is within noise.
Weekly sets per muscle
Hard sets per week for every muscle, counting indirect work such as triceps on a press. A front and back body map shows what is under target, in range or high.
Exercise suggestions with their evidence
When a muscle is short on work, Setrung suggests exercises from a catalog graded by the strength of the research behind each one, with the citations a tap away.
