Good strength but be careful on your pulling. If you check the video above you can see that as soon as you start the pull your shoulders are forwards over the bar; this will cause the back to round as soon as the bar comes off the floor and your lower back takes over with taking the brunt of the weight.
Just something to be aware of as I've seen lifters blow the their backs out because of this. Get your shoulders pulled back (which will also help to stop your lower back from rounding), take the slack out of the bar just before you pull, focus on leaning back towards your heels and drive down through your legs; the deadlift can essentially be viewed as just as much of a press as a pulling movement from the role that the legs play with maximal lifts.
Just looking out for you, no doubt your coach is picking up on these kind of things anyway
Keep up the good work with the training MF.
