The BEST exercise you’re NOT doing (but should be): This move hits your adductors, glutes, deep core, and all the stabilizers that keep your knees tracking, your hips steady, and your stride strong!! Start with short holds → build to longer sets → add in some movement → thank me later when your runs feel smoother, stronger, and way less injury-prone. Save this for your next strength day! ___ #runhappy #marathontraining #runnerstrength #copenhagenplank #strongrunners #injuryprevention #runningtips #strengthtrainingforrunners #plank #planks
