Righto, two weeks ago I couldn't do one chin-up, after a couple of weeks in the gym, I can do a couple - and I mean proper ones... I'm struggling with push-ups though, I've never been able to do them - I'm now 21. It's embarressing but I'd rather get laughed at on here than at the selection centre. What can I do? If I could do one or two, I'd probably just keep going until I can do more, that's what I plan to do with my chin-ups anyway..
