I worked out today something interesting, I reckon I can bench more one off weight for a pb without a spotter to annoy me. I use a power rack with the safety bars so Im not concerned about squashing myself (more worried about looking like a dill dropping in on the safety bars). Since joining this forum and reading this sticky particular I have gone from struggling to get a set of 5x5 at 100kg to being able to get the set and getting a pb of 120kg. The 120 I did myself, I got one of the trainers to spot me this morning to try for 130 (I couldn't do it), a couple of things I worked out in hindsight. I wasn't ready when he was so I wasn't in an ideal position when he helped me unrack, which brings me to the second point, I don't like the idea of being helped to unrack, I like to know if I can lift it up in the first place, when I did the 120 I did that 2 or 3 times before I attempted the lift. On the weekend when no staff are there Im going to try the 130 again and see how I go.
