Simply stand with or without weights in your hands. Find your neutral posture, engage your core and bend to your right side. Utilize your core and your feet rooted to the floor and return to the start and then repeat on the other side. We aren't looking for any rotation here. Keep your legs active as you bend side to side. Option: you can step on your exercise band or tube and hold on to the ends for a different resistance as well. Add a balance challenge by changing the position of your feet. Example: staggered stance or tandem
