ur an idiot, how does squats help ur core, it helps ur glutes and hamstrings
basically go to the weight room, bench, squat, work ur biceps and triceps and shoulds and back, dont just do like benchin or ur arms, u gotta make sure u include ur shoulders and back because then wen u start to lift one part of ur body will get much stronger than the other and you will start to perform workouts wrong and hurt urself, also cleaning helps
drink a lot of water, you dont need any supplements, just make sure u eat stuff with a lot of protein n shit in it
for days that you lift hard, run hard also, dont lift hard one day n then run hard the next, your muscles need to rest so make sure u lift and run hard on the same day, have prolly 2 days rest where you run easy n lift light
if u wanna do somthin so you can run faster for longer then really work your core, wen people run the first thing that breaks down is their core, if you do simple crunches, leg lifts(from lying down, 6" off ground and hold), wall sits, platforms(basically pushup position but on ur elbows instead of hands), n w/e other exercises you know for core will help you keep ur form running and not breakdown so easy, the other half of it is just running a lot n gettin used to running for a long time
