Connects to a STRUGGL training ledger to read your athlete profile, sessions and weekly hard-set volume across 17 muscle groups, and to log or schedule workouts. Public calculators cover Hyrox run splits, race-time prediction and estimated 1RM strength tiers.

Example request: "Log today's back squat sets and tell me whether my weekly leg volume is on track."

How to connect: Not in Muse's Connectors list yet, but Muse can still use it. Paste this into Muse: "Use STRUGGL Hybrid Coach to help me. It is a free service with an MCP server at https://struggl.singandclap.com/mcp. It does not need an API key. Ask me before you share anything with it." Muse asks before it shares anything with the app's site. Meta does not review apps used this way, so only use ones you trust. We tested this in the Muse app on September 24, 2026: Muse used an app's link directly this way and returned a live answer.

Tools:
- get_profile: Read the authenticated athlete's biometric profile (bodyweight, height, sex, primary modality, training phase, weekly time budget) and upcoming race goals. Requires Bearer token.
- get_sessions: List the athlete's completed and planned training sessions over the last `days` days (1–90, default 14) or on a specific `date` (YYYY-MM-DD). Call before prescribing today's workout.
- get_muscle_volume: Audit this week's effective hard sets across 17 muscle groups (1.0x prime mover, 0.5x synergist, RPE >= 6 gating) against evidence-based MEV / MAV / MRV weekly volume landmarks.
- log_workout: Record one COMPLETED exercise into the athlete's STRUGGL ledger (with duplicate-write protection, automatic PR tracking, and 17-muscle weekly volume accounting). Call once per exercise.
- plan_workout: Schedule one PLANNED exercise on the athlete's STRUGGL training calendar for `date` (YYYY-MM-DD). Only schedule when the athlete asks for it; call once per exercise.
- hyrox_pace: Public calculator (NO token needed): compute Hyrox 8x1 km compromised run splits, target pace band, estimated total race time, and Riegel 10k/Half/Marathon predictions from a 5 km time.
- strength_benchmark: Public calculator (NO token needed): compute piecewise Wathan e1RM, bodyweight/sex/age-adjusted strength score, tier (untrained -> elite), and kg needed for the next tier from one set.
- interference_tax: Public calculator (NO token needed): audit a weekly hybrid training schedule for AMPK-mTOR concurrent training interference (<3h high / 3-6h moderate window), 36h long-run glycogen depletion before legs, 48h heavy hinge recovery before speed runs, back-to-back quality runs, and S
- volume_audit: Public calculator (NO token needed): audit a weekly lifting split across all 17 muscle groups using fractional set accounting (1.0x primary mover, 0.5x secondary synergist, RPE >= 6 hard-set filter) against Schoenfeld & Pelland MEV / MAV / MRV landmarks.
- hyrox_splits: Public calculator (NO token needed): compute all 8 compromised Hyrox 1 km lap splits (with preceding station fatigue multipliers, Pro/Doubles offsets, and Lap 1 overpacing blow-up cost) from a standalone 5K time using STRUGGL's 200,000-finisher decay model.
- plates_zone2: Public calculator (NO token needed): convert a reference set (weight x reps @ RPE) into piecewise Wathan e1RM, Zourdos RIR/RPE working weight (accounting for bodyweight on pull_up/chin_up/dip), exact gym barbell plate pairs per side, and Tanaka + Karvonen Heart Rate Reserve Zone 
- hyrox_autopsy: Public calculator (NO token needed): post-race or simulation Hyrox diagnostic — compares actual 8x1 km run splits and 8 functional station times against empirical compromised pacing targets and P25-P75 station variance benchmarks to pinpoint exact time leaks.
