Hello! I just started my new cycle consisting of 80mg tren A and 40mg TEST A eod. My objective is to cut, so I want to incorporate some cardio to lean up better and also keep heart healthy. I just bought a stationary bike for the purpose and I'd like to do hiit to get it done quickly and efficiently. Anyone can recommend a good program? I plan to do something like 15 mins 3 times a week. Thank you guys!
