list_alt Step-by-Step Instructions
Sit on the ground with your knees bent and feet flat on the floor.
Hold the medicine ball with both hands in front of your chest.
Lean back slightly, engaging your abs and keeping your back straight.
Slowly twist your torso to the right, bringing the medicine ball towards the right side of your body.
Pause for a moment, then twist your torso to the left, bringing the medicine ball towards the left side of your body.
Continue alternating sides for the desired number of repetitions.
warning Common Mistakes
Recruiting larger muscle groups to "help" move the weight instead of isolating Abs — swinging momentum or shifting the torso takes tension off the muscle this exercise is meant to train.
Locking out too fast or letting the elbows drift outward under load — controlling the eccentric (lowering) phase is where most of the muscle-building stimulus happens.
Skipping a warm-up set at lighter load/intensity — even "beginner" exercises benefit from a rehearsal set to groove the movement pattern before working sets.
person Who Should Do This Exercise
Assisted Motion Russian Twist is classified as a Beginner strength exercise, so beginners and anyone new to training Waist can perform this exercise safely with light load or bodyweight while learning the movement pattern. It fits well in programs focused on strength training and pairs naturally with other Waist movements in a balanced routine.
