This profile by Bill Pierce is an excellent way to begin building endurance, either as part of the base-building phase in a periodized training program or as a moderately challenging workout for people returning to exercise after taking some time off. At the time of this posting in May 2020, this is going to be one of the profiles instructors will want to turn to as they resume teaching following global gym closures and cancellation of classes.
This profile is extremely flexible, enabling instructors to make it harder or easier for their participants, depending on their current level of fitness and goals.
This is another great profile!! Thanks so much!
