Dymatize Project Mass Trainer: Cycle 3, Microcycle 6, Day 108
If you need a rest day, take it! Or, if you really want to push your limits at the end of this trainer, sprint with everything you've got and go for broke!
You're nearly to the finish line! Today, you can choose between complete rest or a celebratory sprint workout. If you still have a lot of remaining energy and feel excited as you near the end of Project Mass, then give today's cardio workout everything you've got. Your improved conditioning should make it a breeze.
Multiple sets of 10-30 second sprints doesn't seem like a lot of work, I know. But don't be tempted to do extra. You've been putting your body through a lot over the course of this trainer, and our goal is building muscle, not shredding. The cardio workouts I've designed will actually do a lot to keep your heart healthy and your muscles growing, despite their brevity.
