What weights should I buy for the 30 day shred?

[Rassy]

Have decided that I can no longer avoid doing the 30 day shred! However, what weights should I get to use with it?

2k hand weights

i haven't shredded for a month but i had 1kg bean bag ones from tesco and a 0.5 from john lewis to go with it, depending on how strong i was feeling

i have these. I use all of them depending if i am doing strength or cardio bits of the workout

I have a set of 1kg, 2kg and 3kg weights (these in fact). I mostly use the 2kg ones, but there are a couple of things I struggle with unless I go down to the 1kg weights, and one exercise where the 3kg ones are best (in Level 3 one of the moves requires you to support yourself on the actual weights, and it's only really doable with the physically bigger dumbells).

Many thanks for the tips!
