A bodybuilding log that shows what's actually growing
Hypertrophy is a volume game: enough hard sets per muscle per week, repeated for months. Most logs store your workouts; IronPack answers the question that matters - is every muscle getting enough this week?
Volume per muscle, counted honestly
Every exercise in IronPack carries a contribution map: a full set for prime movers, half a set for significant secondaries. A bench press credits your chest fully and your triceps and front delts partially; a chin-up pays back and biceps. The weekly heatmap totals those fractional sets per muscle and shows each one against maintenance and growth-zone landmarks tuned to your training age. Warm-ups never count. Free, forever.
Built for accumulation work
- Supersets: link exercises and logging alternates between them automatically.
- Routines: build your split and reuse it; 3 user-created routines free, unlimited on Pro, and installed programs never count against the cap.
- Setup notes per machine: seat height, pin, cable position, remembered where you need them.
- A deep exercise library with muscle-based search, custom lifts, and free form guides with photos and cues.
- Full-body weekly bonus: land every muscle at maintenance volume and the game pays you; land every muscle in the growth zone and it pays more. Balanced programming is literally rewarded.
The depth, when you want it
IronPack Pro (US$3.99 a month or US$29.99 a year, 14-day trial on annual) adds the analysis layer serious bodybuilders actually use: 12-week muscle-group trend charts, per-exercise strength trends, a hard-sets heatmap that weights volume by proximity to failure (via RPE or estimated reps in reserve), and regional focus analytics that split pressing and pulling by angle. The base heatmap and all your data stay free; Pro is the microscope, not the gate.
Common questions
How is volume counted?
Fractional sets per muscle: 1.0 for prime movers, 0.5 for significant secondaries, warm-ups excluded. The mapping is visible on every exercise's page in the library.
What is free vs Pro, exactly?
Free: logging, the weekly set-count heatmap with zones, records, standards, 3 routines, the whole game and social loop. Pro: trend charts, hard-sets heatmap, regional focus, unlimited routines.
Supersets and rest timers?
Both, plus lock-screen rest alerts and per-machine setup notes.
