Alright, this is my first post here. I'm looking for some helpful advice. I'm 25 years old. Six feet tall, and 180lbs. I've been working out for a little over four and a half years now. When I first started I was kinda discusting looking. I had very little muscle and a little extra fat on me. When I first started working out, I stripped a lot of fat off me. I went from 180lbs, to 155lbs. I have put on around 25lbs of muscle in four years. I am a good size now, and I'm solid as a rock. But I have always had trouble cutting. I've made a few attempts at it, and I ultimately fail because I don't see the results that I'm looking for. The main purpose of this post is to find out how I should be lifting while I'm cutting. Normally when I try to cut, I lift the same way I always do. I work out two muscle groups a day, doing 6 or 7 lifts a day, 5 or 6 days a week. I also do 40 minutes of cardio every day that I lift. When I lift I try to change my routien all the time. Ie: doing different lifts, switching my reps to anywhere between 6, 8, 10, and 15, depending on the weight I'm lifting. Should I stick to a certain number of reps? I've always been told that when cutting you should be lifting low weight and high reps. But I've seen really tone people in the gym lifting really heavy weights doing only 4 or 5 reps, so I'm confused. How should one lift while cutting to obtain optimum results?
