Building muscle requires progressive overload, volume, and consistency, but true strength—both physical and mental—is forged through brutal training sessions that push you to your limits. These three workouts are designed to test and develop your muscular endurance, strength, and mental resilience by incorporating scientifically-backed training principles.
1. The Death Circuit: High-Intensity Resistance Training for Strength and Endurance
High-Intensity Resistance Training (HIRT) is an advanced method that builds strength while improving metabolic conditioning. Research shows that combining resistance training with minimal rest periods increases muscle hypertrophy and endurance while maximising calorie burn post-workout (Paoli et al., 2012).
Workout Structure
- A1: Deadlifts – 5 sets of 6 reps at 85% 1RM
- A2: Pull-Ups – 5 sets of max reps
- B1: Bulgarian Split Squats – 4 sets of 12 reps per leg
- B2: Dips – 4 sets of max reps
- C1: Sled Push (40m at bodyweight load) – 3 rounds
- C2: Burpees – 3 sets of 15 reps
Science Behind the Workout
Deadlifts and pull-ups build maximal strength, split squats improve unilateral balance and hypertrophy, and dips enhance pushing strength. The inclusion of sled pushes and burpees increases cardiovascular demand, fostering mental toughness by forcing you to push through fatigue. HIRT has been shown to improve anaerobic power and increase muscle fibre recruitment (Hiscock et al., 2018).
2. The 10-Minute Density Challenge: Maximising Work Capacity
Density training involves completing as much work as possible in a fixed time frame. Studies suggest that high-intensity training performed in constrained time periods significantly enhances muscular endurance and mental resilience (Pareja-Blanco et al., 2017).

- 10-minute AMRAP (As Many Rounds As Possible):
- 10 Barbell Thrusters (60% of bodyweight)
- 10 Kettlebell Swings (32kg/24kg)
- 10 Box Jumps (24-inch/20-inch)
Science Behind the Workout
Barbell thrusters are a full-body compound movement that spikes heart rate and builds explosive strength. Kettlebell swings recruit the posterior chain and boost hip power, while box jumps develop plyometric strength. The time-constrained nature of this workout challenges mental fortitude, requiring sustained intensity without a defined endpoint. Research has demonstrated that density training improves time efficiency and leads to similar hypertrophy effects compared to traditional resistance training (Schoenfeld et al., 2015).
3. The Strongman Gauntlet: Unconventional Strength and Grit
Strongman-style training incorporates odd-object lifts and carries, testing brute strength, grip endurance, and mental determination. Studies show that loaded carries and maximal strength lifts contribute to greater neuromuscular adaptations than traditional weightlifting alone (Lake et al., 2012).
Workout Structure
- A1: Farmers Carries (Bodyweight in each hand, 40m) – 4 rounds
- B1: Atlas Stone Lifts (Heavy, 3 reps) – 5 sets
- C1: Yoke Walk (2x Bodyweight, 20m) – 3 rounds
- D1: Sandbag Over Shoulder (100kg/70kg, 5 reps) – 3 rounds
Science Behind the Workout
Farmers carries build grip endurance and full-body strength, Atlas stone lifts develop hip drive and core stability, and the yoke walk enhances brute force production. Sandbag work replicates real-world strength demands, forcing adaptation under stress. Studies suggest that odd-object lifting enhances functional fitness and real-world carryover strength (Winwood et al., 2014).
