My SLDL's are a fair bit stronger than my regular deads, I was doing around 145 x 6, and now I'm stuck around 130 x 3-4 on regular's because my grip always gives out..
Curious as to number of exercises, sets, and rest times of your workouts Birds?
Sounds a lot like the high volume training I do atm.
Btw, the new equipment looks sweet, I wish my gym would buy some kettlebells... Hell, we don't even have resistance bands.
Hoping a PTC Canberra is in development haha
