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.

The wall ball is a classic CrossFit movement that combines a front squat and an explosive throw, targeting your legs, shoulders, and lungs in one fluid motion. It’s a staple in any high-intensity wall ball workout, known for quickly elevating your heart rate.

In this workout, wall balls build endurance, coordination, and full-body power. Whether you're using a 10 or 20 lb ball, this simple movement delivers serious results — especially when the reps start adding up.

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 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 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.

The overhead lunge combines lower-body strength with upper-body stability, making it a full-body movement that builds core control, shoulder stability, and leg endurance. Common in overhead lunge workouts, it challenges balance and mobility under load.

In this workout, overhead lunges train unilateral strength, improve posture, and reinforce strong, functional movement patterns. Whether performed with a barbell, dumbbell, or kettlebell, the overhead lunge is a powerful addition to any training session.

The bar muscle-up is a high-skill gymnastics movement that combines a powerful pull-up with a dip, taking you from below the bar to above it in one fluid motion. A highlight of many bar muscle up workouts, it demands upper body strength, timing, and core control.

In this workout, bar muscle-ups challenge your grip, pulling power, and technique—making them a true test of gymnastic capacity. Whether strict or kipping, the bar muscle-up is a milestone movement in CrossFit and functional fitness.

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.

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.
