Strengthen Your Whole Body Good runners condition their whole bodies. The arms drive the legs. Keep your upper body and core toned with a lot of push-ups, pull-ups, sit-ups, and back raises (don’t forget that the back is part of the core). Stay away from machine weights and stick to Pilates, climbing, and dynamic flexibility work like yoga. . . . . #nike #nikecanada #niketoronto #nikemontreal #offwhitenikevancouver #nikeshoes #nikewomen #nikewomenshoes (at Toronto, Ontario) https://www.instagram.com/p/CBSiRbPFE-z/?igshid=ibj017es3uqw
