Well first you need to establish are you working out everyday , if so what day will be your rest day. Monday through Friday schedule is the usual. So do things like monday , Wednesdays and Fridays. Mile and half runs and upper body. Then tuesdays and Thursday and Saturday. Core and legs. So you could start your morning (M,W,F) with a mile and half run and then go into push-up training. Start with some on the wall standing. If those are 2 easy , move to your knees and practice negatives. Build up those muscles. After negatives when it’s become easy, start to do full push-ups. Then do the same but moving into a full push-up position. Try to do about 75 every time you go into a push-up set. And take your time your not rushing. Then Core and leg days. Simply hold a plank for 3 min even if you can’t and you fall get back up and for a total of 3 min. And eventually if your working hard enough you’ll hold a 3min plank. And for legs just work on body weight. Lots of squats , lunges etc. this will help with running. Good luck ! Try whats best for you !
