It's back! We are dedicating December to core strength. It's the off-season for many runners and the perfect time to focus on strength, especially building up core strength. Runners need a strong core in order to maintain efficient form, protect their back and take some of the burden off their legs.
This week, we are focusing on planks and side planks. We added in some mountain climbers to get the heart rate up. Feel free to add in another set of mountain climbers. Do this 3x a week and slowly build up to 30 seconds. It's not about how long you can hold the plank, form is more important.
