What is SYSTM (4DP)?

Wahoo SYSTM uses 4DP (Four-Dimensional Power) profiling instead of the traditional single-number FTP to characterize cyclists across four energy systems: Neuromuscular Power (5-second sprint), Anaerobic Capacity (1-minute max), MAP (Maximal Aerobic Power, 5-minute effort), and FTP (sustained power, 20-minute effort). The full-effort test protocol includes sprints, a 5-minute all-out effort, and a 20-minute sustained effort to build a complete power profile. All SYSTM workouts then auto-adjust their targets to your 4DP profile — a workout targeting anaerobic capacity uses your AC number, not a percentage of FTP. Plans are designed by professional coaches including Neal Henderson (coach of Olympic gold medalists).

What SYSTM (4DP) Doesn't Do

Cycling-focused platform — limited running, no triathlon, no multi-sport training plans

The 4DP test is extremely demanding — many athletes cannot complete it properly, leading to inaccurate profiles

Requires Wahoo SYSTM subscription — training library and plans locked behind paywall

Workouts are structured but not AI-adaptive — they follow pre-set plans, not real-time performance adjustments

What AiTrainingPlan Adds

Multi-sport training across running, cycling, triathlon, HYROX — not limited to cycling

AI adapts workouts in real-time based on performance, recovery, and readiness — not static pre-set plans

Power profiling does not require a single grueling test — builds profile progressively from regular workouts

Integrates recovery, sleep, and nutrition data to optimize when and how hard to train

Feature Comparison

Aspect SYSTM (4DP) AiTrainingPlan
Power Profiling Four-dimensional: NM, AC, MAP, FTP from dedicated test Progressive profiling across multiple energy systems from regular training data
Sport Coverage Primarily cycling with some running content Multi-sport — running, cycling, triathlon, HYROX, and hybrid training
Plan Adaptation Pre-set plans from professional coaches AI-adaptive plans that adjust daily based on performance and recovery
Recovery Integration Workouts follow schedule regardless of recovery Training modified based on sleep, HRV, and readiness data
Testing Burden Grueling full 4DP test required for profiling Profile builds progressively — no single maximal test required

The Verdict

Wahoo SYSTM's 4DP concept is genuinely innovative — training to four power dimensions instead of one produces better results for cyclists. AiTrainingPlan extends this concept to multiple sports and adds AI adaptation, recovery integration, and progressive profiling without requiring a single brutal test.
