I'm with you. I'm on the third and final week of this phase, and they have not gotten easier! I feel like my arms are too short or something. I manage four or five, then I'm seriously just resting on my head (which cannot be good for the neck!). Weird exercise - maybe Jillian threw it in there to be edgy and outrageous. I've convinced myself that holding wheel is effective.

She's trying to train triceps/biceps, they work both. Basically it is the reverse of the down dog push-ups. If you don't like wheel you can either just hold wheel or do the down dog pushups instead. Don't stress over it, if you don't' like one move just sub in the other!

I recommend some good training gloves. I wear Under Armor's CTR training gloves and they're awesome at gripping the hand weights and keeping my hands dry.

As far as the wheel push ups, I agree they're definitely hard. I am on my last week of BR and I still cannot do them. If you look at Natalie in the back, I basically just do what she does. Not necessarily holding wheel but holding myself up at the top of my shoulders. Just can't do it. Hopefully will be able to do it after I start the program over.
