I quite often try to ignore the timer and just look at the green bit. As long as I’m keeping it green…
I certainly like trying to distract myself. So smiling to relax my jaw. Pushing my shoulders down. Adjusting grip is a good idea like you mentioned. Checking my knee alignment. Wiggle my toes. Deep breathing.
And then hopefully that’s another minute down, but it’s probably a few seconds 
Keep it green
