Stretch, stretch, stretch!!! Gotta stretch the gastrocnemius. Take a step fwd then bend the back leg (down so your glutes are closer to floor) and keep the fwd leg straight. Keep that leg extended for 15 sec. Then lift your toes toward the ceiling and try to touch your toes with the leg still extended for 15 sec. Switch legs.
I made this workout cuz I read these heel walks could help. Not sure if it's helping, maybe i need to do it more often....
For me I also feel that sitting at a desk with no shoes on a hard floor aggravates my shin splints. I set a pad down to rest feet on.
I've read a lot of stuff on the internet about how to prevent & treat shin splints... Rest, Ice, anti inflammatory meds, not stopping completely but easing more slowly into running (the rule of tens), paying attention to your stride (shorter stride, landing on middle of feet rather than heel or toes), stretching of shins by sitting with feet under you & leaning back with butt on foot, tipping leg up.
I have yet to consistently enough try them all since my pain comes and goes and I'm not really a runner anyway.
stretches is a good way to help, but shin splits can also be caused by the shoe your running in. Just because you are wearing a sports shoe, doesnt mean its good for running. might wanna check and see if its meant for running? if not, nike free runs are very good! :)
