A common but incorrect assumption, only Calorie deficit's will get you "cut" All the working out in the world won't do anything if you don't cut calories in line with a target weight for the amount of work you are doing.. lifting light with lots of rep's doesn't burn near as much calories as you might think. Lift for strength do cardio to burn calories.
I typed up a big thing on my exp lifting for 15 years, then realized nobody would listen or care anyway LOL so I'll summarize and everyone can take it or leave it.
1. COUNT Calories
2. EAT FOOD, supplements, protein powders etc are ALL garbage.
3. Workout and do your cardio before you eat anything, usually this means early morning, the upside of this is directly after that you can eat any garbage you want (fitting inside your calorie target) and it won't hurt you one bit, in fact the "More Junk" it is, the better. I know many will want to argue this one, that is fine, I don't care.. I could explain, I'm not here to teach though. I just giggle when I see people eating the "POWER" bar before trying to get cut by working out for a couple hours.
4. Water, 3x more then you think you want or need...
5. High rep/High set workouts are not what you think they are, 99% of everyone isn't a body builder and don't have the fortitude to be one so don't try, low rep/low set/HIGH weight will be better for you in the long run LEARN what proper form is, Build Strength... the cardio will take off the body fat along with meeting calorie targets.
6. HIIT for cardio is better then long endurance training (and has just been proven to be so)
Take these for what they are, MY experience.. While I have had great training at times in my life most of what I have learned is through trial and error.. I know some people will not agree and that is fine. I don't argue about lifting on the interwebs anymore
