What kind of exercises are in the Michael Mullan hero workout?

  • sit-up

    Sit-ups are a classic core exercise where the athlete moves from a lying position to an upright seated position, engaging the abdominal muscles throughout. A common feature in sit-up workouts, this foundational movement builds endurance and strength in the front of the core.

    In this workout, sit-ups target the rectus abdominis and hip flexors, improving trunk flexion and midline control. They’re easy to scale, require minimal space, and can be performed for reps, speed, or volume—making them a versatile choice for conditioning and core development.

  • Double under

    The double under is a jump rope skill where the rope passes under your feet twice per jump, building coordination, speed, and cardiovascular endurance. It’s a popular movement in high-intensity double under workouts, often used to spike heart rate and improve timing under fatigue.

    In this workout, double unders challenge your footwork, rhythm, and breathing, making them a key tool for improving overall conditioning. Whether you're linking sets or working on consistency, double unders are a fast-paced way to level up your engine.

  • power snatch

    The power snatch is an Olympic-style lift that trains explosive strength, speed, and full-body coordination. Featured in many high-intensity power snatch workouts, it involves lifting a barbell from the ground to overhead in one powerful motion—catching it above parallel.

    In this workout, power snatches improve hip drive, shoulder stability, and barbell cycling efficiency. Whether performed light and fast or heavy and technical, the power snatch builds serious strength and athleticism.

  • clean and jerk

    The clean and jerk is a foundational Olympic lift that develops full-body power, coordination, and strength. A key movement in many strength and conditioning programs, the clean and jerk workout combines a pull from the ground (clean) with an explosive overhead lift (jerk).

    In this workout, clean and jerks train your hips, legs, shoulders, and core, making it one of the most effective lifts for building athletic performance. Whether performed heavy for strength or light for speed, the clean and jerk is essential for total-body development.
