KB forearm work!
 

This should provide ample burn in the forearm muscles:

Great additions today Babs.

I couldn't do those.... Not enough tattoos.

When I buy a Tommy Tippy mug (kiddies cup with lid ;)) then I may try these, until then I think I'd like to keep the hot drink IN the cup. :D I really think these would make the hands shake afterwards, if taken to excess, but they do look interesting as well.
