Hi guys, im just starting out in calisthenics, but im getting tired really quick which disturbs my workout program, therefore i want to start stamina training but i dont want to lose weight because im already thin (i'm 5.7 feet/ 173 cm and weigh about 130 lbs/ 59 kg). Is there any way i could gain weight, stamina and mucle while doing both, or does anybody have any advice/tips on my topic? (btw i eat 3-4 meals a day)
