Liz - I believe you can do 1kg on each side of the bar for the entire Pump class, that should be your first goal . As you told me, your DS weighs 8.5 kg now, so you can't tell me you are unable to lift a measley 2kgs eh?? (The challenge is on - you CAN do it!!).
Leesa, that 1/2 - 3/4 of the class was the first time managed that before having to drop the weight (my kegs weren't going to hold out)
