Unbalanced barbell walks are an amazing way to work the core and can be a great way to help rehab back, hip or knee pain.
It’s similar to how a suitcase carry works were you are just carrying a KB and loading one side. However with the unbalanced barbell walks has the weight hanging using a resistance band which causes even more instability whilst you walk.
Give this a go and see how you get on to really switch that core on.
Try a 20m walk on the left side, then repeat on the right - 3 rounds for quality.
