Dymatize Project Mass Trainer: Cycle 1, Microcycle 4, Day 28
If you need a rest day, take it! You have a long road ahead of you. Don't kill yourself in order to brag to your friends about your work ethic. Listen to your body.
Congratulations on knocking down another three hard training days! I want you to do at least one day of cardio per microcycle during Project Mass, but that doesn't have to be today. You'll have another chance after the next three lifting days.
If you're completely spent from the last three days of heavy training, take the day off. Allow your body to recover from the work, and repair for tomorrow. This trainer is not easy, so you'll have to learn how to listen to your body. As you get stronger, you'll be able to handle more work. When you start to feel more conditioned, you can up the intensity of your weekly cardio session or knock out two sessions per week.
If you choose to take a rest day, you don't need to include the post-workout meal in your nutrition plan.
