Looking for ideas for small group training for older adults.
There are many partner exercises that work great with bands: ie: facing each other rows, back to back chest press. My student (who are in that age group) also enjoy warding type drills for the core: One example; 2 partners share one band, each holding a handle, they keep the lower body still and do arm circles. There are numerous variations you can do with this including keeping upper body still and lunging or tapping feet back or sideways.
As Nancy suggested it is a good idea to switch the partners around. No one wants the dud partner!
