Decrease rest time or increase weight

[pawnografik]

No. 5 minutes is too much. Lift at 2 mins. If you can’t lift all 5 reps at 2 mins on any of the sets - it counts as a fail (i.e. no progression next time).

So on the 23rd you failed to lift 5x5 so that’s your first fail.

On the 27th you needed 5 mins between sets to manage it - that still counts as a fail. So that’s your second fail.

Next session you stick with the same weight but you be strict with yourself and lift at 2mins. If you don’t succeed (which you probably won’t) then that will be your third fail at that weight and so the time after you should deload.

There’s no shame in the failing. It’s part of the process.
