I love sports and do a lot of things. I like cycling as cardio, so I ride my bike several times a week. I also play basketball and tennis. Now I have been going to the gym for more than 2 years and doing powerlifting. I lift different weights to exercise different muscle groups. I've gained a good amount of weight, but for some reason my progress has stopped. I've already tried a lot of things like revising my training plan, diet and rest. I take various nutritional supplements like amino acids and vitamins, but it's all in vain. I'm afraid to give up training because of demotivation.
