Ok so I've been doing deadlifts once a week on back day 5 sets of 6 reps in which first two sets are usually a warmup.
1st set: 135 lbs
2nd set: 225 lbs
3rd set: 315 lbs
4th set: 345 lbs
5th set: 365
I was hoping my grip strength would increase each week but it always gives out before my back and legs do. Any tips on how to increase my grip strength so I can get a full workout to failure before my grip gives out? As of right now I'm planning on gripping a bar with 315 lbs or more every day I go to the gym. Any other good ideas?
