It's too often that cyclists directly focus on their legs and disregard the rest of their body. "If you have a strong core it will increase your power to your pedals, increase your endurance, allow you to be more comfortable on the bike (specifically reducing lower back pain), take corners more efficiently and have a more efficient pedal stroke." says Lee Agur, from I Love Bicycling. Obviously I'm no professional, but I'm here to remind you to make sure you add in some core work for better results on the bike. I won't even pretend to coach you, because I wouldn't know where to begin, but I do know there are countless articles (like this one) out there with plenty of ideas and plenty of YouTube videos to help you out! I also recommend a stability ball, as those are some of my favorite workouts to do!
