100lb one arm rows holding a variation of a #zejax forward #plank. Just experimenting but very tough! And very hard to hold! Also our isometric exercise for the day from our 30 days of isometrics challenge! Almost anything with the Zejax has an isometric component and is awesome to begin with. Why do it? This is about training for strength in compromised, difficult and unusual position where your leverage and stability are taken away. Don’t forget our brand-new DVD on Isometric supersets!
