Muscles

A map instead of a table.

Twelve muscle groups colour along with your sets. Set your own set goals and the map shows where you stand.

  • No goal: the brighter, the more sets
  • With a goal: green on goal, yellow too few, orange above
  • Grey: your plan still brings you to your goal this week
  • Front and back, or a list per muscle
  • This week or averaged over 4 weeks, without pause weeks

Every set counted right.

A set counts for the main muscle of the exercise. Helping muscles don't count.

Balance · Your strength · Where your reps land

  • BalanceYour completed sets across five groups. Calf work counts under knee.
  • Your strengthWhether you are getting stronger. For each exercise the app takes your highest estimated 1RM per week, as in Strength trends, and compares your last 2 completed weeks with the weeks before. Exercises you do more often count more.
  • Where your reps landOver the last 28 days, from ten sets onward. Timed sets have no reps and do not count.

Is it going the right way?

  • Strength trend per exerciseYour highest estimated 1RM per week for one exercise, from working sets of at most 12 reps. If a week only had longer sets, the best of those counts; estimates above 12 reps are less precise. Volume shows the kilos you lifted per week instead.
  • Volume per muscleThe weight lifted per week for one muscle group: weight times reps, summed over your completed working sets where this is the main muscle. The set count next to it counts only those sets too. With two dumbbells, both count.
Records · MilestonesFree

Your heaviest set per exercise, exactly as you did it. A 1RM estimate is something else: it combines weight and reps into a single number.
