We at UP see running and cycling as inward growth activities to be done with passion and not for sweat torture. Neither running, biking, or walking up a stair machine are ever needed to exercise or even improve your running or cycling goals. Doing this activity as your exclusive fitness regime at any indoor facility will never lead to longterm body transformations or improvements in strength, and may hasten any knee injuries. From barreling down that mountain trail, to charging through a marathon, only a proper muscle foundation built up with scientific strength training will provide you with the best chance at smashing any goals and reducing your chance for unnecessary injury along the way.
I love running/cycling & you don’t have treadmills/bikes?
