Introducing the Grouse Strength Loop
At Grouse we’re always working on ways to make your training clearer, so you can see steady progress and results that last. That’s why we brought in the Grouse Strength Loop (GSL), a four-month cycle that takes you from foundational work through to peak strength. It applies across all our strength classes, which cover chest press, squat and deadlift.
Let’s run through the structure.

Phase 1: Foundation & Stability
- Focus: Balance & Base-Building
- Rep Range: 12-20
- Intensity: 6-7
The first phase, Foundation & Stability, lays the groundwork. The month is about balance and base-building, with a higher rep range and lower intensity. Plenty of single-side work builds a base that gets your body ready for the harder, heavier stuff later. Expect your stability and general strength to come up.
Phase 2: Muscle Growth
- Focus: High Intensity & Volume
- Rep Range: 8-12
- Intensity: 8-9 (75% of your 3RM)
Phase 2 shifts to Muscle Growth. This one’s about intensity and volume. With a rep range of 8 to 12 at around 75% of your 3RM and short rest between sets, the aim is to build muscle, pushing close to failure for real gains in size.
Phase 3: Power & Endurance
- Focus: Strength & Stamina
- Rep Range: Power: 4-8, Endurance: 15-20
- Intensity: 7-8
Phase 3 blends Power & Endurance. It runs power work at low reps (4 to 8) alongside endurance work at higher reps (15 to 20). Holding a steady intensity, you build explosive power while also building the staying power for longer efforts, so you come out strong and hard to wear down.
Phase 4: Peak Strength & Performance
- Focus: Maximum Strength
- Rep Range: 3
- Intensity: 8-10 (85-100% of your 3RM)
The last phase, Peak Strength & Performance, is the top of the cycle. Intensity is high, up to 100% of your 3RM, with a low rep range of 3, heavy lifts and solid rest between sets. After a proper warm-up and activation, you’re into maximal work that pushes your top-end strength.
Why the Grouse Strength Loop?
The GSL gives you more transparency in how we plan classes, so you know what’s coming through the year. Cycling through the four phases keeps you challenged and moving forward. It runs on a bouncing intensity, with Phases 2 and 4 heavier and Phases 1 and 3 lighter, which leaves room to recover and grow.
Continuous Improvement
To keep things moving, we base your weights on your 3 rep max (3RM), which we test three times a year. That keeps your targets current and moving with you. Over a full loop you build a base, add muscle, work on power and endurance, and finish at your strongest. It’s the kind of progression that’s built to last and hard to lose.
How to Use the GSL for Your Goals
The Loop is also a tool you can point at your own goals. With three cycles a year, you’ve got room to tailor how you train. A few ways to go about it:
- Focus on one lift all year: if there’s a particular lift you want to get good at, give it the whole year. Cycling through the phases three times keeps building your strength, power and endurance on that lift until it’s dialled in.
- Change the lift each loop: if you want to be well-rounded, pick a different main lift each cycle. Chest press first, deadlift second, squat third, say. You bring up a few areas across the year and it never gets stale.
- Or just train all three: don’t overthink it. Keep moving the needle on all three big lifts and you’ll make progress every loop. The options above are just ways to switch things up and keep the target moving.
Line your training focus up with the GSL and you can plan your progress and hit your goals with less guesswork. Whether you zero in on one lift or spread it across all three, the Loop gives you the structure and progression to keep improving.
