If you’re searching for the ultimate workout program to achieve massive muscular growth, look no further—German Volume Training (GVT) is a time-tested system that’s as torturous as it is effective. Rather than overcomplicating your routine, the philosophy of GVT is simple: subject your body with enough volume to force it to grow.

Ten sets of 10 repetitions. Big multi-joint exercises. Slow, four-second eccentrics. Limited rest. Rinse and repeat.

By blasting that much volume and time-under-tension onto your muscles, you’ll create an unmatched stimulus for muscle growth and repair. You’ll flood your fibers with blood to generate a superhuman pump. You’ll create massive hypertrophy in your slow-twitch muscle fibers. On a biological level, you’ll also increase the mitochondrial and capillary density within your slow-twitch muscles to recover better between sets and become fatigue-resistant.
