So my kids really into skateboarding as of the last coupple months.. so old dad had to get back on a board too ofcourse. I rode from about age 5 - 16 every day - literally. Skateboarding was life and eventually left behind all other organized sports to focus all my time on that. So here we are almost 20 years later and probably 60 plus lbs heavier. WHAT A WORKOUT just pushing to the store is. Im not sure whats more tiring the left leg balancing and holding up 200+ lbs or the right from pumping. Either way im getting some insane cardio from this and utilizing ALOT of little stabilization and fast twitch muscles that havnt been touched in ages.
