I am 36 years old, 5'11", and 208 lbs. Got out of the army rangers and decided to start powerlifting in the civilian world to stay in shape. I did my first deadlift workout ever and got 275 for 5 reps after alot of warmup sets. My form is probably horrible because it felt like my spine wanted to pop out of my lower back. But, is this a decent weight for just starting deadlifts? Kind of bummed because I thought I could lift alot more. Do gains come fast with deadlifts? I was thinking around 500lbs was the average deadlift.
