You’ve likely heard that hardgainers should eliminate cardio entirely. While there is some logic to this argument, it’s not entirely true. When done correctly, there is a place for cardio in a hardgainer’s program. Plus you never want to ignore your most important muscle: your heart. Big muscles don’t stay big long in a coffin. You want to put on size and stay healthy.
For optimal results, keep cardio to low or moderate intensity for 20-to-30 minutes. Two or three cardio sessions per week will keep your heart healthy, improve nutrient delivery to muscle cells and may even boost your recovery time.
