Ive read that deadlift is a very taxing exercise and it may be wise to miss it here and then to allow the body some real rest,

example: last week, my max is 170kg and I did 3 successful sets of 8 reps at 130kgs with only 1.5 minute breaks, my lower back was ultra sore for 3 days and any form of rolling on the ground felt great lol, I was little sore for the another 2 days,

Then this week I 3 x 8 x 135kgs with 3 minute breaks and I'm hardly as sore, cause I had 3 minute breaks which im going to stick with.

Should I leave deadlift every 3 or 4 th week?

Or should I keep going hard until there is reason to rest?

Thanks Cya
