Are kettlebell swings good for me if I have low back pain?
As with any exercise we need to think about if it is the right tool to use at the right time.
The kettlebell swing is a dynamic hip hinge movement and the hip hinge movement pattern is often used as an exercise in back pain and lower limb exercise programs.
As this is more dynamic its best to be guided by your physio about when and if to introduce this exercises. The dynamic component may aggravate someone if they have not mastered hip hinging and bracing or their condition is still quite irritable. However this does not mean it should not be used. Being able to perform dynamic movements with load may actually form part of how you bullet proof your low back.
As such its best to incorporate the kettlebell swing after time spent building up low back and hip strength with alternative hip hinge exercise.
Is there a difference between single handed and double handed kettlebell swings ?
The 2 arm kettlebell swing is easier to learn and is the first variation to be taught. It teaches us how to hip hinge, how to maintain a neutral spine under load, and to develop strength and power in the legs.
The 1 arm kettlebell swing is more advanced because it increases the stability required to maintain the neutral spine in a dynamic loaded movement. You have to work harder with the core and trunk to prevent too much rotation as you swing.
How do i get started with kettlebell swings ?
- Maintain a flat back (neutral spine)
- Keep chest up
- Keep neck in a neutral line.
- Sit on slightly flexed knees.
- Brace your abdominals
The movement comes from the hips, the arms stay relaxed and essentially just act as hooks.
- Swing the kettlebell back bringing the wrist to inner thigh (don’t go further back)
- Engage the hips to push the kettlebell forwards.
- Relax arms and let kettlebell swing naturally upwards.
- Snap the hips forward and squeeze glutes to lockout
- Keep the arms straight
- Swing to chest height
