After some pretty painful lumbar disc problems, I dead lifted for the first time in two years last night and totally surprised myself. Started with just 100kg on the bar, fully expecting to struggle but found myself flying up to sumo-ing 140kg for a really easy 8 reps. Not big numbers by any means but I was chuffed at how I'd maintained a lot more strength than I expected. Hoping to crack 200kg again by mid July.
I'm guessing that the sheer volume of upper back, hamstring and glute work that I've been doing has helped me maintain a certain level of relative strength.
