seriously the only form of exercise I look forward to. feels more like exploring and enjoying the weather/scenery, gets you more in tune with the city, and suddenly it’s been an hour and you've gone 20 miles. you dont need to break the bank and get a top of the line micro-carbon-fiber italian roadbike that weighs half an ounce or anything either, plenty of used bikes are at shops or on facebook marketplace for a good price. all cardio and NONE of the joint pain, my hips are gonna love me in my 50s and runners stay mad about it
