Might give this a ganTuesdays and Thursdays 7pm at Lambton Street do a fitness/boxing session. It's good like, only £3. Do a bit of fitness and also do some pad work, bags, sparring, technical stuff, etc. all relaxed atmosphere and no dickheads. If you are any good they will train you up for the team if you were looking to take it further.
Lambton Street boxing been about as long as I can remember (and im old).
