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 BikeErg is a fan-powered cycling machine that delivers a smooth, low-impact workout focused on leg power, aerobic endurance, and pacing control. Common in BikeErg workouts, it's perfect for both steady-state conditioning and high-intensity intervals.

In this workout, the BikeErg builds quad and glute strength, while challenging your engine and recovery. Whether you're sprinting for calories or logging meters, the BikeErg is a versatile tool for improving cardiovascular fitness in a joint-friendly way.

Knee raises are a core-focused gymnastics movement that builds abdominal strength, hip flexor control, and grip endurance. Common in beginner and advanced knee raise workouts, they’re performed hanging from a pull-up bar, bringing the knees toward the chest.

In this workout, knee raises train midline stability and coordination, making them a great progression toward toes-to-bar. Whether strict or kipping, knee raises are an effective and scalable movement for developing strong, functional core strength.

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.

Knees to elbows is a gymnastics-based core movement performed hanging from a pull-up bar, where the knees are driven upward to make contact with the elbows. Frequently featured in knees to elbows workouts, it trains core strength, grip endurance, and body control—all under tension.

In this workout, knees to elbows develop midline stability, lat activation, and coordination, serving as a foundational skill for more advanced movements like toes-to-bar. They’re an effective way to build functional core strength while improving shoulder and hip mobility in dynamic settings.
