Which of the following exemplifies an active recovery day after heavy squats?

An active recovery day is designed to promote muscle repair and replenish energy without putting additional strain on the body. Light sled drags serve this purpose effectively because they involve low-intensity movements that can increase blood circulation to the muscles worked during heavy squats. This circulation helps to remove metabolic waste products, enhances nutrient delivery, and decreases muscle soreness. Engaging in light activities like sled drags encourages movement without the intensity associated with heavy lifting or high-impact cardio exercises, making it an ideal choice for active recovery.

In contrast, complete rest may not effectively facilitate recovery as it limits blood flow and movement, which could prolong soreness. Heavy lifting is counterproductive on an active recovery day as it adds more stress to the muscles that have just been intensely worked. Cardio sprints, on the other hand, involve high intensity and can lead to fatigue, rather than promoting recovery. Therefore, engaging in low-intensity activities like light sled drags is essential for recovery while still keeping the body active.
