On rest and recovery days it is important to avoid doing the worst thing you can do for your body... nothing. Examples of rest and recovery activities are walking, static stretch exercises (after a warm up and loosening up period), dynamic stretching, swimming, water running, and riding a bike.
High intensity work is great but itâs as stressful to the body as strength training. So itâs hard to recover from. Low intensity work actually enhances your recovery between hard training sessions. So make some time at least 2-3 days per week to go for a long hike, walk, bike ride, etc. for 30 minutes. Ideally, you want your heart rate to be at 65-70% of max (220 minus your age) during this session. I prefer to do this first thing in the morning. The added benefit is that you get exposure to sunlight.
