i work anywhere from 70 to 80 hours a week, i get at best 2 hours breaks during the afternoon on weekdays, saturday mornings and sundays off.
been thinking about dedicating some time into doing some bodyweight/calisthenics stuff which, as far as i can tell from whats on google, is something i can do at home (obviously dont have time to hit a gym on weekdays, and saturday morning/sundays id rather go jogging/cycling i guess) with minimal equipment (if i have to spend a couple hundred euros on some stuff at a sports store thats np tho)
other than sit ups/lunges/push ups and squats (pull ups too if i can fix a bar at home), what should i be doing? this is basically for beginner before i move on to more complicated/harder stuff, so any written/video guide or useful material in general would be really helpful. Goal would be to build up some muscle/resistance, i'm rather skinny eh. any info regarding food to go for/avoid for this kind of activity is also welcome
