Suggestions for F 60yrs looking to build some strength? A friend of mind wants to essentially start from scratch with core strength- just enough to stay in good shape, nothing too serious.
At that age, joint (particularly wrist) mobility and strength is weak, so high strain exercises are out of the question. At least for the near future.
I was thinking hollow holds, low progression v sits and perhaps some planking.
Any suggestions would be greatly appreciated -core or other muscle group related.

Thanks
