i've been training consistently for about 4 months now and I've seem to hit a wall. I'm fatigued, not losing weight, and pulling muscles every week after my bjj classes. When i started, I was 220 lbs. I'm only 5'9" so i felt really overweight. After about 2 months of training, I lost 16 lbs but have not lost any since. In the last few weeks or so, I have also noticed fatigue and lack of recovery in my muscles. I have improved on the impact of my workouts. Before, I would just do some light cardio and then do some strength training. I would do this 2-3 times a week. Now, I workout every other day, usually something different each day. Some days I weight train, some days I hike, some days i do circuit training, and bjj 1-2 times a week. I guess my question is that I'm having a hard time keeping up with my nutrition. I really want to be able to support this kind of routine with proper diet and supplements, but i'm having a hard time with it. My goals are to lose about 20 more lbs. any help/advice would be greatly appreciated. i'm really trying to train like an athlete would and not as a casual hobby. btw, i'm 29 years old.
