I'm having difficulties with my windmills, in particular when lifting the weight in my left hand. I have some suspicions on what causes me trouble, but I would like the opinion of someone with more experience (i.e., pretty much anyone here).
In the vid below, I only did 2 reps on each side to keep it short, but I usually do 5 reps on each side. I'm using 25lbs. The last two reps are on my weaker side.
Many thanks!
