It seems like every week, I have 2-3 questions related to workin out, and I know many other people probably wonder about the same things. So I guess I'll just keep em in here, as long as the thread doesn't get too old. Any help is appreciated. Also, anyone else who has questions can put them there, and if I do happen to have any idea on something, I will answer it. 1. I always figured that doing the bench press and push-ups were working the same exact muscles, and that one would help the other. However, I hadn't done push-ups in about a month, and I was doing the bench press 2-3 times a week. I definitely felt stronger on the bench, and I am able to push about 30 pounds more than I was when I started a month ago. I did push-ups for the first time in over a month on Wednesday, and I did more than I used to do, although I still felt fatigued a bit. I have been sore since then...and usually, when I do push-ups, I'm only sore after not doing them for a long time...so it wouldn't suprise me if I hadn't done the bench. So the question is.....is there a major difference between what you do on the bench and what you do for push ups? Can you do both the same day, or should you space them out? 2. How much should you work your biceps if you are trying to gain size on them? For the last month and a half, I've mainly been doing arm curls with 25 Pound dumbells. When I first started, I could do about 3 sets of 4, and now I am doing about 3 sets of 10...and I usually do them 2-3 times a week, spaced out with days. Am I doing enough, or would it hurt to do more than this on the days that I work them out? If I did these 3 sets in the morning, would it hurt doing the same or something different later on in the day? 3. I hear that crunches target the abs more, and that sit-ups target more muscles around the abs. Is this true, and is there a maximum to how many of either you should do? 4. I guess it's due to genetics, but my calves seem to stay the same damn size, regardless of how much I work them out. I have been using a machine that puts whatever weight on you that you chose. I have seen many people do different things...one guy would start at 400, do 10 quick reps, then drop 10 pounds and do the same over and over til the pounds got to 200 or maybe lower...some guys will do a set number of pounds, and do 3 sets of 15 slow raises. I've been doing enough to where 3 sets of 20-25 reps seems to be enough to make me feel it...but the calves don't look any larger at all. Is there anything else I should do, or should I stay patient with that? 5. When training leg muscles, which ones will help you to run faster? It seems like when I run, my hamstrings seem to feel the most sore, so I'd assume that they are more necessary for running faster. If not, does just practicing to run fast help the most?
