I was going to deadlift 500 lbs by April. I did it on January 2nd instead. It is certainly possible to be too conservative in your goal-setting. I’m the proof. Are you really testing yourself? Just something to think about.
Also, this looked beautiful in my head, but is a really ugly deadlift. If you’re looking for instructional material, do not try to mimic the deadlift you see here. I won’t be going any heavier until I can do this with better form.
Get after it.
