I personally don’t mind running, however the area I live in right now is a bit high in crime and there is nowhere I feel comfortable running, however, I like to drive outside the city limits and ruck in the woods when my wife just hikes normally along with me, you can burn 3000 calories in a workout this way, it’s moderate cardio, and it’s good strength training for everything but your arms, and it’s a nice break from civilization. If you’re carrying over 50lbs I can assure you your heart rate will stay very high and it is good for your core.
