Bear Grylls’ Brutal 30-Minute Full-Body Circuit
I Tried Bear Grylls' Brutal 24-Move Circuit Workout — Here's What Happened to My Body
The survival expert's minimalist approach to fitness is as intense as his adventures
---
When you think of Bear Grylls, you probably picture him drinking questionable liquids in the wilderness, rappelling down cliffs, or eating things that would make most of us gag. But behind those death-defying stunts is a finely-tuned machine that requires serious maintenance.
So how does one of the world's most famous survivalists stay in peak physical condition? Not with fancy gym memberships or complicated equipment. Instead, Grylls relies on a brutal 24-move circuit workout that can be completed in just 30 minutes with nothing more than a kettlebell.
I dove deep into this workout to understand why it works, how it's structured, and whether mere mortals like us can actually survive it.

The Philosophy Behind the Madness
Bear Grylls has never been about flash or excess. His fitness approach mirrors his survival philosophy: use what you have, make it count, and never quit.
This workout embodies that ethos perfectly. You don't need a $200/month gym membership. You don't need machines or a personal trainer watching your every rep. You need a kettlebell, your body weight, and about 30 minutes of focused effort.
The format is deceptively simple: 20 seconds of work followed by 10 seconds of rest. If that sounds familiar, it's because this Tabata-style training has been scientifically proven to torch calories and build both strength and cardiovascular endurance simultaneously.
But here's where Grylls' workout gets interesting — and brutal.

The Structure: Six Blocks of Pain
The workout is divided into six muscle-group blocks:
1. Core
2. Legs
3. Chest
4. Back
5. Shoulders
6. Abs
Each block contains four exercises, and here's the kicker: you repeat each block three times before moving to the next. That means by the time you've finished the core section alone, you've already completed 12 working sets.
Multiply that across six blocks, and you're looking at 72 total working sets in under 30 minutes.
Yeah. Brutal is the right word.

The Complete Exercise Breakdown
Block A: Core Foundation
Your workout begins where all functional fitness should — with your core. These aren't your grandmother's sit-ups.
- A1: High Plank Hold — Maintain a straight push-up position, abs and glutes engaged, creating one long line from head to heels
- A2: Plank Knee to Elbow — Alternate bringing your knee to your elbow (same side or opposite) with a controlled torso twist
- A3: Plank Up-Down — Drop from hands to elbows and back up, maintaining hip stability throughout
- A4: High-Plank Superman — From plank position, extend opposite arm and leg while maintaining balance
The goal here isn't just abdominal strength — it's building the stability that prevents injury in every other movement.
Block B: Legs (Where Things Get Explosive)
This is where the kettlebell earns its keep.
- B1: Squat Jump — Hold the kettlebell at chest height, sink into a deep squat, then explode upward
- B2: Kettlebell Pass-Through Split Squat (Left) — In a lunge position, pass the kettlebell around your front leg
- B3: Kettlebell Pass-Through Split Squat (Right) — Same movement, opposite leg
- B4: Kettlebell Swing — The king of full-body exercises; explosive hip hinges that build power from the ground up
These movements don't just build leg strength — they develop the explosive power Grylls needs to scramble up rock faces and sprint away from danger.
Block C: Chest (No Bench Required)
Four push-up variations that will humble anyone who thinks bodyweight training is easy.
- C1: Standard Push-Up — The classic, executed with perfect form
- C2: Alternating Push-Up — One hand elevated, creating an asymmetrical challenge
- C3: Pike Push-Up — Hips elevated, shifting emphasis to shoulders and upper chest
- C4: Close-Grip Push-Up — Hands together, elbows tucked, targeting triceps
By the third round, these "simple" push-ups feel anything but.
Block D: Back (Building Pulling Power)
- D1: Inverted Row — Bodyweight rows under a bar or sturdy surface
- D2: Pull-Up — Overhand grip, full range of motion
- D3: Kettlebell Row (Right) — Single-arm rows for unilateral strength
- D4: Kettlebell Row (Left) — Balance it out
This block addresses a common fitness blind spot: most people push far more than they pull, creating imbalances that lead to injury.
Block E: Shoulders
- E1: Overhead Press
- E2: Kettlebell Hammer Curl
- E3: Overhead Triceps Extension
- E4: Upright Row
Functional shoulder strength that translates directly to climbing, carrying, and real-world movement.
Block F: Abs (The Finisher)
Just when you think you're done, there's one more gauntlet.
- F1: Kettlebell Knees-to-Elbows
- F2: Kettlebell Russian Twist
- F3: Bicycle Crunch
- F4: Superman
This final block tests everything you've built and ensures your core is bulletproof.

Why This Workout Actually Works
1. It's Time-Efficient
Thirty minutes. That's it. No commute to the gym, no waiting for equipment, no excuses. In the time it takes to watch a sitcom episode, you've completed a full-body assault.
2. It Builds Functional Strength
Every movement in this routine translates to real-world capability. Grylls isn't training to look good on a beach (though that's a side effect). He's training to survive — to pull himself up ledges, carry heavy loads, maintain stability on uneven terrain, and generate explosive power when his life depends on it.
3. It Requires Minimal Equipment
A kettlebell. That's your primary tool. Add a pull-up bar or sturdy surface for inverted rows, and you're set. This workout can be done in a park, a hotel room, a backyard, or yes — probably even in the wilderness.
4. The Work-to-Rest Ratio Is Optimized
The 20:10 Tabata protocol isn't arbitrary. Research has shown this ratio maximizes both aerobic and anaerobic conditioning. You're building strength and endurance simultaneously.
5. Progressive Overload Is Built-In
Three rounds per block means fatigue accumulates strategically. By round three, those 20-second intervals feel eternal. As you get stronger, you naturally push harder during each working set.

Critical Form Notes
Bear Grylls is 50 years old and has put his body through more punishment than most special forces operators. He's still going strong because he prioritizes form over ego.
Key points to remember:
- Planks: Maintain a straight line from head to heels. The moment your hips sag or pike up, you're not training — you're risking injury.
- Squats: Keep your back straight and chest up. Depth matters, but not at the expense of spinal alignment.
- Kettlebell Swings: This is a hip hinge, not a squat. Power comes from your glutes and hamstrings, not your lower back.
- Pull-Ups: Full range of motion. No kipping until you've mastered the strict version.

How to Scale This Workout
For Beginners:
- Start with one round per block instead of three
- Use a lighter kettlebell (or no weight at all)
- Take longer rest periods if needed
- Modify push-ups on knees, pull-ups with bands
For Advanced Athletes:
- Increase to four rounds per block
- Use a heavier kettlebell
- Reduce rest to 5 seconds
- Add a weighted vest

The Bigger Picture
There's something refreshing about Bear Grylls' approach to fitness. In an age of $3,000 Pelotons, boutique fitness studios, and endless optimization gadgets, he proves that simplicity still works.
A kettlebell. Your body. Half an hour.
That's all it takes to build the kind of fitness that actually matters — the strength to climb, carry, endure, and survive whatever life throws at you.
You don't need perfect conditions to train. You don't need the latest equipment. You need consistency, intensity, and the willingness to push through discomfort.

Final Thoughts
After researching this workout extensively and attempting it myself, I can confirm: it earns the "brutal" designation.
But here's what I've also learned — brutal works.
The exercises aren't complicated. The equipment is minimal. The science is sound. What this workout demands is something most fitness routines let you avoid: genuine, sustained effort with no place to hide.
That's probably the real secret to Bear Grylls' fitness. Not some exotic training protocol or expensive biohacking technology. Just showing up, pushing hard, and refusing to quit.
Sounds a lot like survival, doesn't it?
