Van show a pic of Robert in a locked pose.
The pose you posted of Robert you can see he is looking down so he can make sure he shows his side glute before he totally flexes his chest.
I told him gets your legs in then go into a pose.This way in the front he flexes his quads, and the back he flexes his glutes.
Alot of guys pose, yet they aren't flexing there legs,and not showing everything they got
Presentation is everything.
In this pose Robert is clearly not in a full pose, he is going into the pose.
So it doesn't not show his detail
