Your plan.
Your timer.
Your training.

A single timed work interval. A session is made of blocks — warm-up, strength work, conditioning, cooldown. Each block has a duration and exercise(s), and runs to a timer that counts down.

A complete workout made up of multiple blocks. The app shows today's session when you open it — the blocks you'll run, in order, with their durations. Once you pick a session, you start the first block and work through them one at a time.

Rate of Perceived Exertion — a 0–10 scale of how hard you worked. 1 is rest, 10 is absolute maximum effort. The app logs RPE after a session so you can track effort over time without needing exact metrics.

Someone who trains across multiple disciplines — strength work, endurance/cardio, and gymnastics or skill work (climbing, jumping, throwing). A hybrid athlete is neither a pure powerlifter nor a pure endurance athlete.

A fitness competition combining running, strength stations, and obstacle challenges. 8km total distance with 8 workout stations (sled push, wall climb, rowing, and more). Popular for testing hybrid fitness in a race format.

Training designed to build aerobic capacity — your ability to sustain effort over time. Usually 20–45 minute blocks at moderate intensity, where you're breathing hard but can still talk. "Kettlebell Engine" or "Bodyweight Engine" are programmes built around this.

A loaded sled on a low-friction track — you push it for distance or time. Tests leg drive and explosive power. Standard in HYROX race prep and strength training.

Explosive movements with a kettlebell — swings, snatches, cleans, Turkish get-ups. Builds explosive power, grip strength, and resilience under load. Kettlebell Engine is one of WW hybrid's built-in plans.

Stationary assault/air bike or similar — typically used for high-intensity intervals or steady-state aerobic work. Friendly on joints, builds leg power and aerobic capacity.

A double-pole ski machine that works your entire upper body and core. Used for conditioning blocks and aerobic work, especially in HYROX prep.

Rowing machine (C2 or equivalent). Full-body pull movement that builds power and aerobic capacity. Used in both steady-state and high-intensity intervals.

An upper-body pulling movement from a bar — unweighted or weighted. Tests pulling strength and is often included in fitness competitions and hybrid training.

An explosive leg movement — jump from the ground onto an elevated box. Tests lower-body power and coordination. Often done for max height or as repeats.

Climb a vertical rope using hands and legs. Tests grip strength, pulling power, and full-body control. Standard in HYROX and fitness competitions.

Your primary training location — where you have access to full equipment. The app can suggest substitutions if a session calls for kit you don't have in other locations.

A secondary location with limited equipment — typically a rack, dumbbells, maybe a bike or pull-up bar. Sessions adjust to what you've flagged as available.

A minimal-equipment setup for when you're away from your primary gym. The app can build sessions using just bodyweight and light tools.

WW hybrid's foundational 6-week plan. Blends strength density work, conditioning, and mobility across upper and lower body. Good entry point for anyone new to hybrid training.

Two levels (Beginner and Performance) designed for HYROX race prep. Emphasises the specific movements in a HYROX: sled push, wall climb, rowing, and endurance.

A strength-focused interval: 4 minutes of heavy work, 4 minutes of light recovery, repeated 4 times. Built for explosive power and aerobic resilience under load. Pairs strength with high-intensity conditioning.
