Long answer - There are the competition totals published on the net these days, so you'd be able to make direct comparisons. The main British Feds are BWLA, BPC and BPO and finally BDFPA

There are two other factors: equipment (lifting shirts and suits) and steroids (tested or untested Federations). Using or not using these makes a huge diffrence to your total lifts.

Try to get along to a meet and see what its all about, get chatting to people there about training and techniques etc. From there pick a future contest and prepare for it. Once you've lifted, you will never look back. 30 is a great time to be starting, you've yet to reach your peak.
