I'm an amateur boxer. I'm 22. My hole life I've been underweight and weak. By age 17 I was 6' and weigh 115lbs. So I made a choice. I dedicated my life from there on to inproving my weak body. So I began lifting weights and drinking protein shakes. After a whole year of very hard work I only put on a mere 7lbs. I was frustrated, I thought I had to push myself ever harder then. After a lot of fail methods and countless hours of reading online I finally understood that it was my diet. I just wasn't eating enough. By that time I fell in love with boxing. I wanted to box so I began training for it but after many injuries to my muscles I felt like I needed to quit boxing until I gained more muscle. A year after I gained about 25lbs of muscle. Now I'm at 160lbs. I started taking boxing again about 4 months ago. Stopped lifting weights cause my trainer told me it would interfere with my training. And while.I am managing to keep the weight its becoming harder and harder now. And while I'm getting better in terms of technique, my cardio, endurance and even body is getting weaker. I'm eating great, I'm sleeping good and I'm taking my vitamins but it seems not to be enough. I'm training real hard yet I feel stuck and worse, weak. I don't have enough endurance or cardio. I need to inprove but nothing I do seems to work no matter how hard I train. (sigh) Im just really tired of spending all this time and money on my body for it all to blow up in my face after all the hard work, pain, sweat and tearsI've never used steroids before but I feel as thats about to change soon.
