My program's design is to build strength, not necessarily endurance. I add five pounds a work out as long as I can perform the exercise with good form. (5 sets of 5)
Should I change to endurance work with the weight lifting? What kind of reps/sets?
Or would it be better to keep with the heavy lifting with low reps and just do more wind sprints, Tabata, etc.? Say sprints three times a week and tabata every other day?
