I am 5.5 feet, 71kg, waist 32 and my stomatch is out. I recently joined gym and the trainer tells me that we will put on more weight on the upper part like on chest and biceps so when the biceps becomes like 20 inch then we can cut it by work outs and it will stop at 15-16 inches and will be very hard like stone. Is this the right way of body building??? Will i not face the problem of being over weight???? Will i get abs and biceps i wanted ?? Is trainer going the right way ??? Please answer me asap. I am really worried .very worried.
My recommendation is to set up a healthy diet and work to build muscle and burn off the weight you currently have on your waist. There is no need to go "off season" per say when you are just starting out. You don't have enough muscle mass to get rid of it efficiently. There are many bodybuilders who don't even add any more to their calorie intake but just to maintain, but that's further down the road. For now, stick with a healthy diet and weight train and get to know what works with your body. One exercise can work at one point than not at another. The challenge is to get past your body getting used to a muscle building activity and pulling out another exercise to get it to grow a little bit more. Keep in mind, that we can reach a great physic naturally without resorting to unnatural ways of doing it. So, we may not turn into Ronnie Coleman but you will still feel bigger and this time, it will not be your stomach.
I'm pretty similar dimensions, but bulked up nicely a few years back and have a couple of thoughts:
Your trainer's advice sounds good for rapid bodybuilding, but not for what it sounds like you want (toned body, flat tummy, etc). If he's telling you to do a bicep curl, then drop him and prepare to spend several weekends reading way too much conflicting advice online :)
Muscle burns fat, so if you want to lose fat, it doesn't hurt to do some hypertrophy to build muscles quickly. However, I wouldn't focus too much on dimensions. Your biceps are tiny things compared to the legs/core/back, so building them up will achieve next to nothing in terms of burning fat. Focus on core (deadlifts, squats, freeweights etc), functional training, and as an added bonus you will go into middle age (or further) with a body thats built to work. Trust me, that gets pretty important.
Building abs is frankly impossible. What you need to do is lose fat. This is as much diet as anything else. Once you've built up a good base of muscle, and are moderately fit, shift your focus onto high-intensity sprints, a good clean diet, avoid beers & milk etc. Drink more water, whatever your doing is not enough. I also found tabata sprints did wonders for me, as did a short spurt of going vegan, but you will probably need to experiment to find out is needed at each plateau to keep you going. Also - try to measure your bodyfat (you can get passable bodyfat callipers for about $30), and forget the scales.
tldr; Do a functional workout, get a flat stomach, forget your biceps. By the time you have the tummy, the biceps will look great anyway. Also remember, the faster it comes, the faster it goes. Don't look for miracles, and even after a long winter in front of the computer you'll still be able to flex and find your 6-pack.
