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.

The hang power clean is a dynamic barbell movement that builds explosive power, coordination, and full-body strength. A staple in many hang power clean workouts, it focuses on lifting the bar from the “hang” position (above the knees) to the shoulders — without a full squat.

In this workout, hang power cleans challenge your hip drive, grip, and timing, making them ideal for both strength work and high-intensity conditioning. Whether you're cycling reps or going heavy, the hang power clean develops efficient movement and athletic explosiveness.

The shoulder to overhead movement trains your ability to drive a load from the shoulders to a locked-out position overhead using one of several techniques — strict press, push press, push jerk, or split jerk. It's a staple in any shoulder to overhead workout for building upper body strength, power, and stability.

In this workout, shoulder to overhead challenges your shoulders, triceps, and core, especially under fatigue. It’s a versatile movement that allows athletes to choose the most efficient technique to move weight overhead — depending on the load and intensity.

The burpee pull-up combines a full-body burpee with a vertical pulling movement, delivering a powerful mix of conditioning and upper body strength. Common in high-intensity burpee pull up workouts, it challenges your engine, grip, and coordination all at once.

In this workout, burpee pull-ups spike your heart rate, test your pulling endurance, and require full-body control under fatigue. Whether used in sprint intervals or long AMRAPs, the burpee pull-up adds intensity and variety to any session.
