To hitmandonny:
Aight listen, the biggest misconception people have is that you can 'get bigger while your doing boxing', thats bullshit, you have to take time off cardio and do heavy weighted workouts. The reason why i say this is, because when you do cardio you break down muscle tissue, and when you bulk you build muscle tissue, so you have to choose which path you want. If you want to get bigger abs or arms or watever, you have to take time off. In your next holidays if they go for 1 month or 2months, stop boxing and do heavy weights, if you want bigger abs like you said, do low rep of 6-8 with weights (e.g crunches with a 10 or 20kg plate on your stomach, or leg raise with a dumbell hanging off your feet), (make sure its 3-4 sets perworkout, so maximum 6-7 sets in total per session) and do it 3 times a week. Then when you get back into boxing you can lose all the extra excess fat which you might have put on from bulking, but it shouldnt be an issue anyway. Also make sure you take just as much carbs per day as you are takin protein, and before workout up your carb intake by an extra 20-30 grams.

Then when you get back into boxing, to lean up, be extra strict with your diet around so its healthy foods and no rubbish and junk (even when you bulk u should be strict, but im emphasising that cutting is alot harder), and having good servings of protein and carbs, and as you lean up your abs that you have worked to bulk will start to appear
