Hi, i'm 20 years old, 1.74m, 70kg and about 15% of body fat. Most of my fat is concentrated in my abdominal area and so my trainer said I should run everyday at a rate of 130-150 bmp for 30 mins. I dont usually trust trainers at the gym but I don't know, I can clearly see and feel my body fat and most of it at my belly (specially when i sit down) so im kind of desperate. I usually go to the gym 5 days a week for weight lifting (chest-biceps, back-triceps, legs-shoulders) repeating legs-shoulders only once and leaving 48 hours to heal each muscle, will that 30mins of cardio after my workout (usually takes me about 1 hour only weights) at that rate affect my muscle growth ? will it diminish it ? is it possible to grow muscle while reducing body fat at the same time through cardio ? Tyvm in advance.
