Exercise Logger

A prototype Next.js application for logging exercises with detailed tracking of movements, resistances, and rep configurations.

Note: This is a frontend prototype with no backend persistence. Data is not saved between sessions.

Key Features

Multi-Resistance Support

Unlike typical exercise trackers, this app supports multiple resistances per exercise - useful for niche training scenarios like using two resistance bands per side. Each resistance entry includes:

• Type - Barbell, dumbbell, kettlebell, resistance bands, cables, machines, etc.
• Weight - Optional weight in lbs
• Dual - Whether the resistance is bilateral (e.g., two bands per side)

Extended Rep Type Support

Beyond simple rep counting, the app supports various rep configurations:

• Simple Reps - Standard repetitions
• Hold - Isometric holds with duration tracking
• Tempo - Reps with specific timing for each phase (eccentric, pause bottom, concentric, pause top)
• Concentric Only - Lifting phase only
• Eccentric Only - Lowering phase only (negatives)
• Explosive - Maximum speed/power reps
