Hands of Steel: Boxing Interval Workout | PDF Guide Included

Hit hard, fast and often, even when you're exhausted. Most fighters can throw one or two fast, powerful punches. Far fewer can keep that same explosiveness into round three. Hands of Steel is Coach Firas Zahabi's punching interval system, learned at the Grant Brothers Boxing Gym (home of former world champion Otis Grant) and used to train professional UFC fighters. It's the quickest way to develop explosive punching output, bar none.

Why athletes love it

• ⚡ Hair-trigger hands: go from stillness to full-speed punching in an instant, so you can fire in the smallest windows of opportunity
• 🥊 Power that lasts: short, all-out bursts keep every punch a true sprint, so your speed and power don't fade under fatigue
• 🔥 A fat-burning machine: high-intensity intervals spike your heart rate and keep your metabolism elevated after the session
• 🦵 Easy on the joints: serious cardio without pounding your knees, hips and ankles

What's included

• 🎥 Full follow-along instruction: warm-up, bag work, interval rounds, cool-down and abs
