Logging the way you train

When starting a new workout, tap the date shown at the top of the workout screen. Pick any prior date. The session saves to that date in your history.

You can also edit a session's date after completing it: History → tap session → menu (•••) → Edit date.

In the exercise picker — when adding or swapping an exercise — tap + Add custom exercise at the bottom. Name it, pick the primary muscle group, and pick equipment. The exercise is private to your account.

Once it's in your training history, Kevin can use it in future AI-built workouts.

Tap the exercise header → Swap. Kevin picks an equivalent that fits your gym setup and matches the same muscle group.

You can also swap manually — tap Swap → Browse to pick anything from the catalog. The new exercise carries over your current set count and rep range; Kevin recalculates the starting weight based on your history for the new movement.

Tap a set's type indicator and pick DROP. The row turns orange and exposes a sub-ladder of drop steps. Each step is its own weight × rep entry, indented under the parent set.

When Kevin programs a drop set, he uses your strength baseline and your gym's real plate math — every drop hits an actual weight that exists on the rack (no 47.3-lb dumbbells). Minimum ~10% drop per step or one full equipment increment, whichever is meaningful.

You can add or remove drop steps mid-workout. Log the top set, then log each drop in sequence as you fail them.

Set up a superset by tapping the link icon between two adjacent exercises in your workout plan. Kevin also programs them automatically when you've enabled supersets in Preferences and the day calls for them.

During the workout, the timer pauses between the two paired exercises so you can flow A1 → A2 → rest without thinking. The set counter tracks both exercises in lockstep.

The rest timer slides in as a slim orange bar at the top of the screen the moment you log a set. It never blocks the weight or rep input — you can keep adjusting numbers while it runs.

• +30 / -30 — adjust the remaining time in 30-second chunks.
• SKIP — dismiss immediately if you're ready to lift.
• 🔊 — toggle audio cues (ticks at 3 / 2 / 1, chime at zero).

Default is two minutes. You can change the global default in Profile → Settings → Rest timer, or override it for a single workout from the workout's ••• menu.

Pro unlocks custom rest sounds.

In the exercise picker (when starting a New Workout or swapping mid-session) you have three filters:

• Search. Type any part of the name. "Flat" finds Flat Fly, Flat Bench Press, Flat Dumbbell variations.
• Body region chips. All / Chest / Back / Shoulders / Traps / Arms / Legs. One tap to narrow the list.
• Equipment chips. Barbell / Dumbbell / Cable / Plate-Loaded / Selectorized / Bodyweight. Combine with body region to find "Chest + Dumbbell" (4 results) versus "Chest + Cable" (12 results).

The catalog has 437 movement variants across 174 equipment types. Each one has Kevin's form cue, the primary and secondary muscles, and a YouTube link for the form video.

Can't find what you want? Tap + Add custom exercise at the bottom of the picker. Name it, pick the muscle group, pick equipment — and it's in your library forever.
