As the new year approaches, I'm intent on trying firm up the smooth edges in anticipation of the summer months. I'm planning to incorporate some form of HIIT along with my HST program.
Here's my question on HIIT as it relates to preserving/affecting LBM: Is there an advantage to working multiple body parts in the routine vs. a routine that primarily utilizes one bodypart, such as sprinting or biking which would stress the legs? In other words, will LBM and/or fat loss be more positively affected in the bodyparts worked in a HIIT routine?
