Nope…I wouldn’t take part in anything like CrossFit endurance training. If tomorrow were my last day on this earth, I wouldn’t want to end my life with one of the regular intense CrossFit workouts. A third situation includes few factors that can make intensity prescriptions obscure as well. Like when you stumble into specific exercises for which 1RMs don’t exist at all. Maybe you run into exercises for which 1RMs are not possible or not advisable. Also, there can be such a routines, for which 1RMs have not been tested yet.
