I wrote this article 2 days ago but there was an issue with my ISP so it's a bit late, I can't apologise enough guys.
Yesterday I mentioned that it deserved an article entirely to itself as opposed to smaller answers for the other questions and you're about to see why.
Moobs (man boobs) are a collection of fat around the chest area. How they're formed on boys who aren't overweight isn't confirmed but generally assumed to be hormonal. Most people are pretty self conscious about them, I know I sure as hell was a few years back. Getting rid of them doesn't require all that much effort, just consistency and time like most fitness goals.
First of all, start with a 10 minute light cardio warm-up such as jogging or skipping before you begin. Do NOT forget to stretch between the warm-up and workout.
Exercise 1 - The classic push-up.
I actually began working on getting rid of my moobs after discovering the 100 push-up challenge. They explain it far better than I will so check it out here.
As it says, do it three times a week and do the next exercise alongside them during your chest days.
Exercise 2 - The Bench press.
The good old bench press, one of the most widely recognised weighted exercises around. You know better than I would what weight you should use (do it so that you can knock out a few but are struggling by the end, some trial and error might be required).
3 sets of 8-12 reps.
Exercise 3 - Incline bench press.
It might sound too similar to the regular bench press but it works well in conjunction with the other exercises.
Same as above, 3 set of 8-12 reps.
This part comes down to your personal tastes in terms of cardio, most people will suggest one thing, other suggest another. Personally, I just think you should do what you're motivated to stick with and do something you enjoy. I would mix up jogging/running and swimming on different days depending on my moods.
I'd suggest doing about half an hour of jogging/running and switching intensities every couple of minutes and really pushing yourself for one or two. Do something similar for swimming.
So if you combine a similar workout schedule to this with good nutrition then hopefully, after a month or so, you'll have noticed a definite improvement in your chest area.
Let me know how it goes for you guys!
