Log every set in seconds

Your previous performance on every set

Next to each set, the LAST column shows what you did last time: 80 kg × 8, × 12 for bodyweight, 45 s for a plank. No more digging through your history.

In the settings, you choose where that value comes from: your last workout, whatever the template, or the last workout done from this template. Handy when the same exercise appears in a heavy day and a light day.

Log your sets without closing the keyboard

When you tap a set's load, an arrow appears above the keyboard. Tap it to move to reps, then once more to finish the set: Musku checks it off, starts the rest timer and puts the cursor on the next set. In a superset, it follows the order of the round.

Warm-up, failure and drop sets

To the left of each set, a pill shows its type. Tap it to change it: normal set, warm-up, to failure or drop set. Warm-up sets don't count in your muscle distribution.

Warm-up sets worked out automatically

For a weighted exercise, open the ··· menu and choose “Add warm-up sets”: Musku inserts warm-up sets before your working sets. It works out their loads from the weight of your first working set: by default, 40% × 5, 60% × 5, then 80% × 3.

In the Workout section of the settings, the “Warm-up sets” setting lets you choose the percentage and reps of each set, up to six sets, as well as how loads are rounded: 1, 1.25, 2.5 or 5 kg. A preview shows the result for a 100 kg working set.

Changing your working weight? Choose “Recalculate warm-up sets” in the exercise's menu: Musku replaces the warm-up sets you haven't checked off yet. You can also add warm-up sets from the template editor.

A load to aim for, based on your last workout

Under each weighted exercise, Musku can show the load and rep count to aim for, based on your heaviest working set from your last workout. You know right away whether it's time to go up.

Until you reach the top of your rep range, it suggests the same load with one more rep. Once you hit the top, it suggests adding a step. If you were well below the range, it suggests going lighter. After more than 6 weeks without the exercise, it never suggests going up.

Tap the suggestion to set the exercise's “Rep range” and “Load step”. By default, they depend on the muscle worked and the equipment.

The suggestion is off by default. Turn it on under “Load suggestion”, in the Workout section of the settings, after reading its precautions: it's a calculated guide that knows nothing about your fatigue or how you feel that day. You always choose the load.

The plates to load on each side

When you enter a load on a barbell exercise, Musku shows the plates to load on each side, right above the keyboard: for 80 kg on a 20 kg bar, “Per side 25 + 5 kg”.

In “Bar and plates”, in the Workout section of the settings, pick your bar weight (20, 15 or 10 kg) and untick the plates your gym doesn't have. If a load can't be matched exactly, Musku shows the closest one. Rather do the maths yourself? Turn off “Show plates to load”.

Your perceived effort, set by set

RPE rates the effort of a set on a scale from 6 to 10. 10 means no more reps were possible, 8 that you had about two left.

Turn on “Show RPE” in the settings, Workout section: an RPE column appears on your working sets. Tap it and pick your value, in half-point steps. The column doesn't show on warm-up sets, nor on cardio and planks, which are measured in time or distance.

You then find “RPE 8” next to the set in your history, even if you turn the column off.

Supersets, in your template or mid-workout

A superset chains two or more exercises with no rest between them. In an exercise's ··· menu, tap “Create a superset”, then tick the exercises to chain. They don't need to follow each other in the workout: a “Superset A” pill links them.

When you check off a set, Musku takes you straight to the next exercise in the round. The rest timer only starts once you've done your set on every exercise in the superset.

Created in a template, the superset comes back in every workout. Created mid-workout, or in a freestyle workout, it only applies to that workout: your template stays as it is. A workout can hold up to three supersets.

Input that fits each exercise

Musku only shows the fields that matter for the current exercise:

• load and reps, for barbells, dumbbells, machines and cables;
• reps only, for bodyweight or resistance bands;
• added weight or assistance, in kilos, for weighted or assisted bodyweight;
• distance and time, for cardio;
• time in seconds, for isometric exercises such as planks.

Adapt your workout as you go

Machine taken? Swap the exercise for another one, without touching the rest of the workout. You can also reorder with a long press, and add or remove sets and exercises.

A bar at the top of the screen shows your progress, one block per exercise. You can shrink the workout into a mini bar to use the rest of the app, then reopen it with a tap.

Notes on every exercise

Leave a note on an exercise, such as a seat setting or a technique cue: it comes back automatically every workout.

A comment on your workout

At the end of your workout, you can leave a comment of up to 200 characters: how you felt, your progress, a pain or anything you want to remember.

This optional comment shows in your history. You can read it in full and edit it at any time in the workout's details. It doesn't appear on your share card.
