.....your 'cutting cycle' will depend more on your diet than the amount of reps you do. Generally though, low reps for strength - high reps for endurance.
Personally, I'd go for twelve and push for fifteen... you're not suddenly going to lose lbs of muscle just because you've upped your rep range. Also.... train with a bit more intensity and focus, remember, you want to lose body fat to look more defined..... and if you look more defined you'll look bigger.... if you've spent time 'bulking up' it's sometimes hard to change that mind set and you feel a little unsure about losing the fat, doing more reps, eating less calories... "ooh, I'm going to get smaller and not be so strong?"
In my opinion the one area that makes the whole picture and finishes the physique..are the abs. Lose body fat and get the abs to show and you'll look so much better.
Don't get caught up with the 'lard asses' in the gym who confuse looking big and fat with looking muscular....sometimes i feel someone needs to just tell them..."look mate..you're fat O.K."
One last thing, it takes time to lose fat... at a healthy rate, because you need fat, you body wants to hold onto it. So give yourself time.
So remember, work with intensity, as soon as you get your breath back... onto the next set....and one last thing, you have burn more calories than you consume....easier said than done.
........you want something bad enough........ you go for it.
Now go, go and become that person you want to be.......
