the lat looks torn to me also, but its not out of the realm of possibility that his rumored tendonitis in his shoulder is affecting his flexing ability… if you notice, his shoulder never seems fully flexed in any of the front shots… (all the MM variations, sanding relaxed to the front)… it might be a stretch but try to flex your lat in those poses without flexing your shoulder (which with serious tendonitis might make it tough to flex as much lean muscle as Ronnie has) its almost impossible
