40 Minute Killer Cardio Tabata Workout - This is such a fun summer workout!! I was so happy to do this one for you because the weather outside was PERFECT! Although, it was windy so I had to turn the sound off :( This will be a Silent Sam workout, no annoying chatter from me!! Well, we'll chat at the end during the stretch ;) This is a no equipment tabata cardio hiit that is perfect for anywhere you go this summer! Let's take a mat outside, find a park or beach and crush this summer workout!
