I find at first its too easy to get overwhelmed with the all of the information there is available.

Basically, the only supplement you need is a good multivitamin. Followed by omega 3 capsules for good health. If you find you arent getting enough protein in your diet, you can buy protein powder. You need roughly 1-1.5g protein per pound of bodyweight. if you weigh 150 pounds, you need 150-225 (roughly, these are just general guidelines) grams of protein. If you can eat it, just supplement it. But food > supps.

Don't waste money on fancy supplements. Its all hype/marketing. Pure 100% creatine monohydrate is something you might want to look into. It is debatable about its benefits and side effects. But other than that, you really don't NEED anything else. Most products are just overhyped concoctions. srsly.

As far as diet goes, try eating 5-6 meals instead of 2 or 3 a day. It keeps your body fueled. Personally, i find it hard to eat that many times a day. I usually eat 3 or 4 times a day. Meh. Im not perfect.

The main thing is just keeping up with the workouts. If you are really, really hurting then your body is saying rest. So rest. But don't stop, and don't be soft on yourself. If your chest is still sore after 4 or 5 days, be a man and hit it again. If its really painful (as opposed to sore) then you might have torn something. Dont make it worse. You can set yourself back months if you have a tear and make it worse.

Your body knows best. Listen to it. After a couple weeks the DOMS (delayed onset muscle soreness) calms down. Theres another point, when you are working out after an hour, and you are new, you might be like "well... i don't feel really sore or tired yet."

this ISNT an excuse to go do like 4 more sets of bench press. Trust me, the next day you FEEL it. You pretty much make this mistake once and you don't do it again.
