list_alt Step-by-Step Instructions
Stand with your feet shoulder-width apart and your arms extended straight down by your sides.
Keeping your back straight and your core engaged, slowly bend your torso to one side, lowering your hand towards your knee.
Pause for a moment at the bottom, then slowly return to the starting position.
Repeat on the other side.
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.
Flaring the elbows too wide or letting the hips sag/pike, which shifts load off Abs and stresses the shoulder joint.
Rushing through reps using momentum rather than controlling both the lifting and lowering phase, which is especially important since there's no external load to force good tempo.
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
45° Side Bend 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.
