Since you are starting from ground zero, I'm going to recommend you start with 95 lbs. The barbell plus 25 pound plates on each side. Just work with that for 10 reps. For two sets. Get a feel for the movement. You don't have to go fast. Maintain your form. A problem I see and sometimes I do is the upper body stays stuck and so the legs continue extending. Now, your body is in a situation where your lower back and hamstrings are trying to complete the rep, not your quads, hams, and glutes. This is not good.What's a good # of reps/sets when you're first starting out on deadlifts?
Then, add 20 lbs. and do 10 reps.
Then add another 20 lbs and do 10 reps. Now you are at 135 lbs.
Keep going up in 20 lbs. increments and do 10 reps each. If you cannot do 10 reps, then do not add more weight to the barbell. Continue doing another set with as many reps as possible.
When you have completed four sets (or seven total), you should have 215 lbs. on the barbell. You can stop.
If you were able to get that weight for 10 reps, what you can do at your next deadlift workout is to start at 135 lbs. and go up in 20 lbs. increments. and do seven sets. When you get heavier, if you cannot do 10 reps in a clean manner, then don't to 10 reps in that set. Do as many as you can. No need to get injured.
Check back in later with your results. I have no idea if this is too easy, just right, or too hard.
