Jerk x 5 + Towel L sit pullups x 8 Workout

M/ 38/ 134 lbs/ 5'-6"
I did a different WOD last night
(the night before I did the weighted pullups & walking lunges with bar in rack position)
last night I did:
couplet (not for time but keep it moving) of:
Split Jerk (from rack) x 5,4,3
Towel Pullups (L position) 8 reps
I was concentrating on GOOD FORM and good speed with really pushing UNDER the bar.

95 lbs x 5 + towel pullups x 6
115 lbs x 5 + towel pullups x 6
135 lvs x 5 + towel pullups L position x 8
145 lbs x 4 + towel pullups L position x 8
155 lbs x 3 + towel pullups L position x 8
155 lbs x 3 + towel pullups L position x 8
155 lbs x 3 + towel pullups L position x 8

towel pullups were GREAT on grip. I need to start adding them for my grip development.
Jerk felt pretty good overall, but I STILL NEED TO CONCENTRATE ON PUSHING MY BODY DOWN UNDER THE BAR.
My neck and back are a little tight. I think I'm shoving my head too far back out of the way and loading up my upper back too much with a little bit of hyperextention in the lowering of the weight
