The throw-down version of the assisted lying leg raise asks you to actively drive the legs back down rather than let assistance or gravity lower them, which loads the eccentric portion the basic raise skips. That's usually where the extra ab burn comes from. It's a natural progression once plain assisted leg raises feel too easy.

How to Do the Assisted Lying Leg Raise With Throw Down

1. Lie flat on your back, legs extended and arms resting by your sides.
2. Tuck your hands underneath your glutes for support.
3. Brace your core and raise your legs off the floor while keeping them straight.
4. Continue raising until your legs are perpendicular to the floor.
5. Lower your legs back down to the starting position.
6. At the same time, snap your legs down toward the floor, keeping them straight.
7. Raise your legs back up to the starting position.
8. Repeat for your planned rep target, maintaining clean technique and steady breathing on every repetition.

Biomechanical & Joint Load Cues

Sagittal/transverse plane shoulder horizontal extension and scapular retraction. Strengthens upper back, rhomboids, and rear deltoids while demanding lower back stability.

Common Mechanical Mistakes & Form Errors to Avoid

• Using Torso Momentum (Jerking): Rocking the upper body aggressively to initiate the pull relies on hip extension rather than the latissimus and rhomboids.
• Incomplete Scapular Retraction: Failing to pull the shoulder blades together at the top cuts off peak contraction of the rhomboids and middle trapezius.
• Flaring Elbows Too Wide: Letting elbows flare 90 degrees shifts mechanical tension away from the lats onto the upper traps and neck.

Proper Breathing Patterns & Core Engagement

Inhale as weight lowers forward. Pull elbows back past torso while exhaling and squeezing shoulder blades together.

Injury Modification & Joint Safety

For lifters with lower back fatigue, chest-supported incline rows or seated cable rows provide equivalent upper-back hypertrophy without spinal loading. If joint irritation persists, immediately stop and substitute this movement with another exercise from the Waist exercises category.

Muscles Worked

The Assisted Lying Leg Raise With Throw Down primarily targets the Abs, with Hip Flexors as the primary synergist muscle group, along with the Quadriceps.

FAQ

What muscles does the Assisted Lying Leg Raise With Throw Down work?

The Assisted Lying Leg Raise With Throw Down primarily targets the abs as the primary agonist. Synergist assistance is provided by the hip flexors along with the quadriceps. Maintaining strict biomechanical alignment ensures maximal tension remains focused on the intended muscle fibers rather than shifting to surrounding stabilizer joints.

What equipment do I need for the Assisted Lying Leg Raise With Throw Down?

The Assisted Lying Leg Raise With Throw Down is performed using a assisted. Ensure all equipment is securely positioned with collars or safety pins locked before loading working sets. If you train in a home gym or minimal setup, explore our equipment-free and resistance band alternatives below.

What is the most common form mistake on the Assisted Lying Leg Raise With Throw Down?

The most frequent error is using torso momentum (jerking): Rocking the upper body aggressively to initiate the pull relies on hip extension rather than the latissimus and rhomboids.. Controlling the 2 to 3-second eccentric lowering phase ensures maximal hypertrophic stimulus while shielding connective tissue.

How many sets and reps should I perform on the Assisted Lying Leg Raise With Throw Down?

For muscle hypertrophy and size, aim for 3 to 4 working sets of 8 to 12 repetitions at 70% to 80% of your 1RM with 90 to 120 seconds rest. For absolute strength development, prioritize 4 to 5 sets of 3 to 6 heavier reps with 2 to 3 minutes rest.

What's a good alternative to the Assisted Lying Leg Raise With Throw Down?

If you don't have access to a assisted, the Arms Overhead Full Sit-Up (male) targets the same abs using body weight instead. This alternative replicates the same joint angle and movement plane while allowing you to train effectively with different available gear. You can also substitute it seamlessly in our free Workout Plan Builder.
