hi guys, first time poster. 7 years vegan, 21 years old, 179cm/5"10', 68.5kg/150lbs im not interested in bulking, but very keen on building lean muscles and lose body fat. i've been doing cardio (jogging for 30-40 minutes) and swimming (30x50m over 45minutes) for about 2 years and i've recently started going to the gym constantly the last 2 months. the changes are obvious, in the sense my arms and chest are getting bigger and more firm when flexed. but my goal is to have very defined muscles, how do i achieve this? should i only be focusing on cardio or going to the gym? i sometimes do cardio on the same day of my gym workout. do i really lose lean muscles from doing these cardio exercises? cheers
