I'm so reminded of when I started my KB workouts. I hated them too. It was hard and uncomfortable. But thank goodness I stuck with it. I wouldn't even be doing yoga right now if I had not gotten in such great shape using KBs.
So I've decided to use KBs to help me get stronger for yoga. I've not been doing any windmills or TGU's so I'll be adding those exercises at least one day a week.
