Welcome to the Iron Core Challenge! For the next 30 days, we will be doing a core variation for 100 reps..or so EVERYDAY. You have a time limit of 10 minutes you are trying to beat. Some of these may only take a few minutes if you choose not to rest. Go to my instagram and tag the gyms page, @ironstrengthandconditioning and my personal account @costalottamoney1 so I can see your hard work! There is no excuse not to do a 3-10 minute workout, anyone can find that time in the day. I challenge you to do this with me to start getting active and start seeing results!
