Burpee to target adds an explosive jump to a fixed height after each burpee, turning a classic bodyweight movement into a test of vertical power and precision. Popular in burpee to target workouts, this variation pushes conditioning, accuracy, and repeatability under fatigue.

In this workout, burpee to target builds cardiovascular endurance, lower-body explosiveness, and mental toughness. The requirement to hit a target—often 6–12 inches above standing reach—forces athletes to maintain power output even when fatigued, making it a staple in competitive functional fitness.

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 Assault Bike is a fan-powered machine that delivers one of the most effective full-body conditioning challenges in fitness. Common in high-intensity assault bike workouts, it trains your legs, arms, and lungs all at once — and responds directly to how hard you push.

In this workout, the Assault Bike is used to build power, stamina, and mental toughness. Whether you're sprinting for calories or holding a steady pace, the Assault Bike is perfect for intervals, finishers, or pure engine tests.

The V-up is a bodyweight core exercise that targets your abdominals, hip flexors, and overall midline control. It’s often used in V-up workouts to build core endurance, especially in high-rep or gymnastic-style training.

In this workout, V-ups demand coordination, flexibility, and explosive core engagement. They’re a great alternative to sit-ups when you want more intensity and a greater range of motion — making them perfect for CrossFit and functional fitness routines.

The single under is a jump rope movement where the rope passes under your feet once per jump. It’s a foundational skill often used in warm-ups, scaling options, or high-rep single under workouts to build coordination, rhythm, and cardio endurance.

In this workout, single unders provide a low-impact, accessible way to boost heart rate and improve timing. Whether you're just starting out or mixing them with more complex skills, the single under is a valuable movement for all fitness levels.

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 atomic sit-up is a dynamic core movement that combines a full-range sit-up with a leg raise or tuck, often performed on a suspension trainer or using bodyweight alone. Featured in atomic sit-up workouts, it delivers a powerful double hit to the upper and lower abdominals.

In this workout, atomic sit-ups improve core strength, hip flexor control, and total-body coordination. The dual movement pattern increases time under tension and recruits more muscle groups than traditional sit-ups—making them a challenging and effective addition to core training or conditioning circuits.
