I know I never did it OUT LOUD... but for all those times I silently scoffed at LISS... I'm sorry!
OMG - 30 minutes at 3MPR and 10% Incline kicked my ASS!! I was drenched in sweat within the first minute and I walked away from the treddy as wiped out as I've EVER been from a HIIT. The last three minutes were HELL!
Thank you Kyra for sugesting it to me.. and thank you ME for finally trying it. Now I need to shower - thank you very much!
