## What is SpotterFuel?

SpotterFuel helps you keep training when your gym is crowded.

Pick the muscle you want to train, choose the exercise you planned, and mark the equipment that is busy or not available in your gym. SpotterFuel gives you practical same-muscle reroutes so you can keep the session moving without rebuilding your whole workout.

Use SpotterFuel to:
- Find quick swaps for busy benches, cables, machines, racks, pull-up bars, and more
- Keep the same target muscle when your first plan is blocked
- Mark equipment as “Not in my gym” so future routes avoid it
- View simple exercise details, equipment, sets, reps, and coaching cues
- Browse a focused exercise library without needing an account

SpotterFuel is built for real gym moments: the bench is taken, the cable station has a line, or your gym simply does not have the machine you expected. Instead of guessing, you get a clean replacement path.

Free users can see the best reroute. SpotterFuel Pro unlocks the full reroute list for crowded sessions.

SpotterFuel is for fitness planning and education only. It is not medical advice. Train within your ability and stop if you feel pain, dizziness, or discomfort.
