If Tinkerbell had a fitness blog, this is what it would look like. The instructor is sparkly, there's no other way to describe her. So here I am thinking, "This will be easy. No problem. She's sweet!" It wasn't... AT ALL. How this woman can be so chipper while inflicting merciless pain on herself and others is beyond me. I actually had to quit at the 4 minute mark because my abs felt like there were daggers piercing my belly. I will try again tomorrow (after I quit crying). I think her series will be my g0-to on days I can't get to the gym and my body will both love and hate me for it. Give it a try (I dare you!) and tell me what you think.
