Will I still grow muscles if i lift weights and take kickboxing cles?

Yes you'll still grow muscle just not as fast. I do cardio once a week now and during the summer I did it three times a week. I still saw results just at a slower rate (bigger muscles that is) cardio will help you get cut though because it'll help burn more calories and enhance your muscles giving you a nice ripped body. Drink protein after your weight lifting workouts and that'll help. If you do the kickboxing just once a week it really shouldn't effect your rate of muscle growth but it you did it 3 times a week or more you'd be losing weight which will slow your muscle growth.
