Some details incase you need them. I'm 30, weigh 182. Havent maxed out for around 2 years but bench was 285, squat 465 and dead 445. I do martial arts and weightlifting about 6 days a week.

Romanian/stiff deadlifts kill my hips, I find it hard to reach 10 reps with 185lb without what I think are my hips getting sore and muscles in that area feeling really fatigued.
Any suggestions of another exercise that is just as good? I already use seated/laying leg curls as my 2nd ham exercise.

Also my left calf is 15" but right is 14.5", what should I do to bring up the lagging calf? extra set or 2 with right leg when ever I work calves? Stop working the left for awhile?
