Is it worth paying the extra £20? (See below)?

I am deciding between these two weight sets:

and

Is it worth paying the extra or are they the same but in a different colour?





Also I was looking at this:

Would it be worth investing in that set instead of the other two? Which of the three are the best buy? Thanks in advance for your answers.

go for cast iron





crome is nice but dearer, for that £20 you could buy yourself another 20kg of cast iron weights from argos





aviod vinyl weights i made this mistake, becuase they are so much bulkier than cast iron you cant get as much weight on the bar. fine at first but as you move onto heavier lifts they will hamper your progress
Reply:£20 would get you quite a few bricks.
Reply:personally id go for http://www.argos.co.uk/static/Product/pa... There cheaper and there the same weight has your 1st choice. Ive got em as well and there not bad, Ive had em for 2years now and i use em at least 4-5 times a day.
Reply:everyone i know uses things like these for a few weeks and then gives up cos its hard to get motivated on your own.





Much better to join a gym
Reply:Depends on how strong you are. i personally think the first one would be ideal. the third answer is also a good product, even cheaper.





it depends if your really strong and could work up to 70kg's. like you said your in a gym so youll able to use them there, so go for the first one, or third person who answerd for price range.





Good luck
