TweetI'me just going to throw this out there greattt. This is just my opinion but if you don't have any energy that is preventing you from doing lower body, you should be doing it. Squats will help you burn fat and build that solid foundation for that six pack to sit on. Dead lifts to man that will definitely rocket you closer to getting a six pack. Train hard as you can every time bro. Seriously those lifts will increase your upper body strength, and core strength. You can do all the curls you want, but you still have to hit those legs.
