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 pull-up is a foundational bodyweight movement that builds upper body strength, focusing on your back, shoulders, arms, and core. A staple in almost every pull-up workout, it's key for developing gymnastics capacity and functional pulling power.

In this workout, pull-ups challenge your grip, coordination, and endurance — especially under fatigue. Whether strict, kipping, or butterfly, the pull-up remains one of the most effective and scalable exercises in CrossFit.

The thruster is a full-body compound movement that combines a front squat with an overhead press, making it one of the most demanding and effective exercises in any thruster workout.

In this workout, thrusters develop leg drive, shoulder endurance, and core stability, all while elevating your heart rate. Whether using a barbell, dumbbells, or kettlebells, the thruster is a powerful tool for building strength, power, and conditioning — fast.

The chest-to-bar pull-up is a high-skill gymnastics movement that takes traditional pull-ups further by requiring the chest to make contact with the bar. Common in competitive CrossFit and advanced chest to bar workouts, it builds upper body strength, pulling power, and grip endurance.

In this workout, chest-to-bar pull-ups challenge your lats, arms, core, and coordination—especially under high reps or in combination with other movements. Whether performed strict, kipping, or butterfly, chest-to-bar is a true test of bodyweight control and stamina.
