I built HybridX in between. The marathon was trained on it, barbell still in the week.

Questions
- What is hybrid training?
- Hybrid training means running a serious program in both lanes in the same week — heavy barbell work and real distance running, in one body, planned against each other. Not a lifting block with cardio bolted on the end.
- Can HybridX build a Hyrox training plan?
- Yes. HybridX programs hybrid circuit sessions — sled work, wall balls, lunges, running between stations — alongside your strength and running days, and manages the interference between all three across the week. Tell the AI you’re racing Hyrox and it plans toward it. The core of the app is still barbell plus distance; Hyrox sits on top of that.
- How does the AI workout generation work?
- Describe what you want in plain language — like “3 lifting days, 2 runs, keep Wednesday free” — and the AI generates a full training week. It reads your recent training (up to the last 12 weeks; on day one, your setup answers) and your goal, then balances the two.
- Why not just ask ChatGPT for a plan?
- A chat gives you a plan once. HybridX keeps it: it reads what you actually logged and what your watch sent back, pushes the runs to your watch, and when you miss a session it offers to rebalance the rest of the week around it. The plan stays true to the week you are really having.
- Can I use HybridX for free?
- Yes. The free tier includes strength and endurance logging, analytics, load tracking, Garmin and intervals.icu integration, and the hybrid score — for as long as you like. The AI planner (workout generation, modifications, and coach chat) is free for your first 14 days, with no card needed. After that it is $9/month — an early-adopter price against the $19 list price, held for as long as you stay subscribed.
- Does HybridX work with Garmin or intervals.icu?
- Both, and both go two ways. Connect Garmin and every planned endurance workout pushes straight to your Garmin Connect Calendar and onto your watch — structured intervals, pace and HR targets ready to execute — while completed activities sync back the same day. On COROS, Wahoo, Polar or Suunto, connect intervals.icu for the same round trip: planned runs land on your watch, finished activities flow back into your plan.
- Will running kill my strength gains?
- Not as much as you’d think. The interference effect is real but manageable. With proper sequencing — not putting a top set the night before goal-pace work — many lifters hold most of their strength at 40–50 km a week. That sequencing is the plan’s job: the hard intervals share a day with upper-body work, so the legs meet them fresh and the day after stays free.
- What is the hybrid score?
- The hybrid score (Hybrid Athlete Score) is a free tool that rates your combined strength and running from 0 to 100. It compares your lifts against StrengthLevel’s 150M+ logged lifts and your run time against age-graded standards. Five numbers, no sign-up.
