A person who thinks the average 45-minute workout is a nap and wants to run until their legs fall off

I did 45 minutes of HIIT and felt like I could’ve ran a marathon. K Fitty is me.

My friend said 45 minutes was enough. I called him a weakling and did 90.

I went to the gym. K Fitty walked in. I ran out.
