My guess is you have a job and are going to school at the same time. You probably looking for some bodybuilding advice that will help you get the results you want, without sacrificing a bunch of time and money.
I'm in the same position. I'm attending college full time and I work around 35 hours per week. With homework and everything I find it hard to make it to the gym sometimes. With that said I always make gym time my priority.
I know school is important and so is paying the bills. Those things don't matter if you're not healthy though. So number one on bodybuilding advice is make the gym a priority.
I have a goal to go to the gym 6 days a week but I knew I wouldn't be able to accomplish that if I didn't get up early and get it out of the way right away. So now I wake up at 5am every morning and the first thing I do is go to the gym.
There's no better way to start the day and you feel a lot more productive through out the day.
I don't have a disposable income to be spending on a bunch of supplements. I have other bills that I need to pay and I need to pay for college (which is ridiculously expensive). Point is that's ok.
Half the supplements that people try to sell you aren't necessary. You can still gain a lot of muscle without buying all the potions they sell. They just want your money.
Keep it simple. Invest in some protein powder, creatine and maybe a pre-workout if you need it. (I know I certainly do in the morning time)
Bodybuilding Advice #3: It's easier to go to the gym when you have a friend or two to go with. You guys can push each other in the gym and help each other overall.
That doesn't mean you guys mess around in the gym, it means you guys help each other out and motivate one another.
Some days you won't feel like going and your friends can be there to help you get to the gym. Other days they won't feel like going and you can help them get to the gym.
Plus it's a lot easier to go to the gym with a group of people than going by yourself.
Just keep it simple. You don't need to overcrowd your brain with difficult workouts or difficult weight lifting routines. Stick to the basics and I promise you that you will see results!
