Kid, listen to me closely:
If you are serious about having a good physique... As in, people turning their head and saying "holy shit." kind of physique... You need to drop the idea of "bulking and cutting" for the next long while and focus on the following:
1 - Find a good program that you can stick to. There are tons out there that are tested and that work (Starting Stregnth, 5/3/1...) - Basically any program that will have you lifting more and more weight for the next several years. Lifting more and more weight is THE KEY to your progress for probably the next 20 years.
2 - Dont neglect your cardio. You dont need to be doing hours, but 2-4 sessions a week of high intensity cardio (I like HII style on the recumbent bike for about 16-20 minutes) is going to work wonders at keeping you lean for the next few years (forever really)
3 - GET STRONG AS SHIT, AND EAT TO GAIN WEIGHT - THIS is THE SECRET to getting that physique. There is a reason guys with huge chests and legs can bench 4 plates per side and squat 6 plates per side. Make sure you are EATING enough to gain, but not so much that you are getting fat (see rule 2)
4 - Eventually, when you are thick as a brick shit house, you can take 16 weeks to cut up. You'll find me 5 years from now and thank me that you didnt cut down to 150 pounds at 7% body fat and instead waited until you were 225 at 12%, and cut to a solid-as-Sears 204 at 7%... TRUST me on that.
Or if you are just interested in looking "fit" or "in shape" or heaven forbid "toned" disregard every I said above, do endless amounts of cardio, and dont focus on gaining strength.
I wish I could go back 10 years to when I was 16 and tell myself this instead of farting around for so long before I stumbled upon these "secrets"
