Watch your diet
It might. Doing cardio, especially before training, is a bad idea if you care about how much weight you are going to lift. These days most high level powerlifters and coaches who are into cardio recommend something like 1-2 LISS session of 15-20 minutes a week. HIIT uses the same energy systems as lifting weights (ATP/CP), but you could just lift more weights. You could try doing submaximal work with short rest periods, basically speed work. There are different way to do this, not just the Westside way. Josh Bryant uses this with his lifters, you can probably find some articles or videos on it. Take a look at this program:
Chad Wesley Smith used to be coached by Josh Bryant, you can see he uses the same method.
