Im quite young(under 21) but hiking as been a huge outlet for my stress. During the first lockdown, weekly hiking was my time of self care. Its also super good for your cardio vascular system. My Vo2 Max raised around 10-15 points from hiking alone along with my overall speed. Hiking is also one of those thing where it indirectly teaches you life skills; sometimes zigzags are the fastest route or slow and steady is faster then going fast and taking breaks.
