A workout logger clients can actually use in the gym.
Capture sets, reps, RPE, swaps, tools, and session context without turning every workout into a text thread.
Saved session context
Sets, reps, load, and RPE stay attached to the workout review instead of scattered across notes.
Built for the workout that is actually happening.
Fit Flux supports the messy reality of training: assigned plans, one-off sessions, coach-led workouts, and athletes who need to keep moving while still capturing useful review data.
Client logging
Clients open assigned workouts, program sessions, free workouts, or saved workout-library entries and stay focused on the session in front of them.
Solo logging
Independent athletes can record the same clean training data without needing a coach-owned plan attached to every workout.
Trainer-assisted logging
Coaches can log with a client from the training floor, then leave the session with useful notes already attached.
Tools stay where the session needs them.
The logger keeps strength, cardio, timed work, EMOM, and AMRAP sessions close to the tools clients naturally reach for between sets.
Exercise history stays in reach
Clients can compare past performance while logging the next set, so progression context does not require another app or another message.
Rest timer
Keep working intervals visible without leaving the workout.
Plate loader
Turn target loads into barbell math before the next set.
1RM calculator
Estimate strength context from the lift that just happened.
Warm-up sets
Build sensible ramps before the working sets begin.
Heart-rate zones
Keep conditioning work connected to effort and intent.
AI Spotter suggestions
Offer equipment or constraint swaps when a coach has enabled Spotter support.
Spotter support stays coach-enabled.
AI Spotter suggestions can help with equipment conflicts, discomfort, or constraints during a workout. The point is not to replace coaching; it is to keep the client moving while the original training intent remains visible.
Example session support
Advisory, coach-controlled, and captured for review.
The saved workout can show that a suggestion was used, so coach review has the full session picture.
Trainer-assisted logging without the cleanup.
When a coach logs alongside a client, the session can start from assigned workouts, program sessions, free workouts, or saved workout-library entries. The value is simple: the session ends with context ready for the next coaching decision.
From floor session to next prescription
The logger keeps the handoff practical and reviewable.
During session
Record sets, reps, load, and RPE while the coach can add useful notes from the floor.
After save
Review what changed, what was completed, and what should be remembered before the next workout.
Saved sessions become coaching context.
The logger gives coaches a clearer review surface after training: what happened, what changed, and what should inform the next session.
