No, we encourage you to train intensely but also rest periodically to recover from the exertions as well. It’s vital to keeping you healthy and allowing you to push next time to new personal bests. Over-training is something we discourage because it does not help you achieve your fitness or health goals and increases the risk of injury. We recommend either a 3 days on, 1 day off approach, but we find that a 5 days on, 2 days off works better with most people’s schedules.
