Pattern
Lateral flexion
Setup
- 01Stand tall holding one dumbbell at your side.
- 02Place the free hand on the hip or behind the head.
- 03Set feet hip width apart.
- 04Brace the core lightly before bending.
Execution
- 01Bend sideways toward the dumbbell, lowering it along the thigh.
- 02Stop when you feel a stretch in the opposite side.
- 03Pull the torso back upright using the opposite obliques.
- 04Finish the set, then switch hands.
Checkpoints
- -The movement is purely sideways, no forward lean or twist.
- -Hips stay level and still; only the torso moves.
- -The dumbbell slides close along the leg.
- -The working side is opposite the loaded hand.
Common mistakes
- -Holding a dumbbell in both hands, which cancels the resistance.
- -Twisting or leaning forward during the bend.
- -Shifting the hips sideways instead of flexing the trunk.
- -Rushing the reps with momentum.
Programming notes
- -Use 2 to 3 sets of 10 to 15 reps per side.
- -Take 2 seconds down and 2 seconds up.
- -Progress load conservatively; heavy side bends thicken the waist.
