Channel: Bodybuilding TV
TL;DR
Professional bodybuilder Mike O'Hearn demonstrates an advanced power bodybuilding leg workout focusing on a blend of high-strength powerlifting and high-volume bodybuilding techniques.
Key Points
- — Starting the workout with heavy power squats: seven sets of four reps at 70-90% of maximum weight.
- — Transitioning from powerlifting squats to bodybuilding squats using a narrow stance to isolate the quads with higher reps (10-20).
- — Performing squats on a machine with a specific form focusing on pushing the hips out to target the quads more effectively.
- — Finishing the quad section with high-rep sets (15-20 reps) and drop sets to achieve a maximum pump.
- — Switching to hamstring work starting with stationary lunges: four sets of ten reps emphasizing the stretch and glute squeeze.
- — Executing walking lunges with weights for 12 reps each way to target glutes and hamstrings.
- — Using leg curls for hamstring isolation, emphasizing a deep squeeze at the top of the movement.
- — Concluding the workout with calf training: five sets of 20 reps, suggesting calf exercises be done frequently due to muscle density.
Detailed Summary
Mike O'Hearn presents an advanced leg training routine that bridges the gap between powerlifting and bodybuilding. He begins the session with high-intensity power squats, performing seven sets of four repetitions at 70% to 90% of his maximum capacity to build raw strength and mass. After the heavy lifting, he transitions to 'bodybuilding squats,' which utilize a narrow stance and higher repetition ranges (10-20 reps) to shift the focus specifically toward quad development. The workout continues with machine-based squats and high-volume finishers. O'Hearn emphasizes the importance of form, such as letting the knees move slightly and adjusting the hip position to maximize quad tension. He incorporates sets of 15-20 reps and drop sets to ensure the muscles are fully exhausted and pumped before moving on to the posterior chain. For the hamstring and glute portion of the workout, O'Hearn demonstrates a series of lunges and isolation moves. He starts with stationary lunges (four sets of ten) to stretch the hamstrings and squeeze the glutes, followed by weighted walking lunges for 12 reps. The hamstring sequence is completed with leg curls, focusing on a strong contraction and isolation of the muscle. Finally, the routine concludes with a dedicated calf section. O'Hearn recommends five sets of 20 reps for one chosen calf exercise. He suggests that because calves are a dense muscle group that is used during daily walking, they can and should be trained frequently—potentially five days a week—to achieve optimal growth.
