Well, I’m just trying to figure out why you have the sprints there at all. For simplicity, let’s say they can be helpful in three situations: 1)Strength/Speed; 2)Hypertrophy; & 3)Fat Loss. Let’s start with hypertrophy, they have the POSSIBILITY of creating hypertrophy, but I wouldn’t take them over deadlifts. Also, I don’t remember seeing them in the “Plan For Success,” so maybe there’s a reason they didn’t put them in there. But to be fair, if I were to do sprints for hypertrophy, they’d be similar to what you’re doing. However, they would need to instead replace one of your weight workouts, if you look again you have 3 leg workouts in 2 days and 4 in the week. Don’t forget recovery. For Strength/Speed, sprints would be a valuable addition, but if I were doing them, I’d change the parameters(ie. 4-8 reps w/3-5m of rest and @ 95-100% max speed or something like that). To be fair, this is a very individualized thing and what you’re doing could very well work for you, however, this is still a hypertrophy phase, not a speed-strength phase. The more energy system work you do, the less growing your muscles will do. Lastly, for Fat Loss, I’d again have different parameters, more along the lines of tempo runs(ie. 100-200m runs @75% w/30s-90s rest for a total of 600-2000m depending on fitness levels and other various factors). But again, this is a hypertrophy phase, and a fairly expensive one, so we want to keep energy system work to a minimum. So, if it were me here’s what I would and will eventually do. Run 1-2 30-50m sprints @95% with 3-4m of rest after a good warm-up and then immediately head to the gym for the AM workout on Monday(your leg day). This is low volume and high intensity because I merely want to MAINTAIN my speed but I don’t want it to interfere with my hypertrophy training. And not AFTER my leg workout b/c my legs would be shot and there a greater injury potential. However, with all that said, it’s your world and I’m just passing through, so make your decision and learn from the outcome. Be objective and measure your leg size, leg strength and maybe even have a friend give his opinion on whether or not you look bigger. But don’t just say, “Oh, I feel great” and then not make progress. Remember what King said: “Don’t do what’s possible, do what’s optimal”. Or something like that, anyway, let us know what happens.
