The benefits of outdoor exercise are numerous, and not limited to just physical health. Studies have shown that spending time in nature can reduce stress, improve mood, and increase cognitive function.

Activities like running, hiking, and cycling can also be social and enjoyable ways to spend time with friends and family.
