How hard are you working?
This is an amazing thing to me, I see it every day. How hard people think they are training and how hard they actually are working. Our jobs as trainers is to have people do things they think they can't and we know they can. So the question becomes why can't they do it on their own? I feel there are a few reasons that really stand out.
2. Lack of confidence
I never tell a new kettlebell client what Kg bell the are using, because it really doesn't matter. All they should be worried about is the form. It is my job to give them the correct weight. If you have a person use an 8kg bell and don't tell them that it is 18 pounds they don't think it is to heavy. After they find out it is 18 pounds they will tell you that it is to heavy. The weight they have been using for 3 weeks is now to heavy for them. FEAR and LACK OF CONFIDENCE!!!
The good news is that both things can be reversed. As they become more confident they fear less.
So what is holding you back?
Think of it like this. If you take a 180 pound man and a 180 gorilla and tell them to jump from this tree to that tree, who is going to do it and who isn't? Why? FEAR! The gorilla just does it because it needs to get over there. The man on the other hand fears what would happen if he doesn't make the jump.
PS. if you never jump you never know
