It hurts until a point and then it doesn’t get any worse
Running not only requires strong legs, it needs a strong upper body and a solid core. Well, you can absolutely go up to a point without either of them being super-strong but to push further, your base needs to be strengthened, take that from me. Upper body is what could keep pushing you forward when the legs are done and the job of your core is to simply convert that little push into a step forward, and a step more, and a step more…
I’ve never been a gym-junkie so I do some workout-at-home to take care of this aspect of my training. Mind you, these are all body-weight exercises and therefore don’t require anything except that of a yoga-mat and a tiny-teeny bit of determination. Today, my routine included:
~100 rope skipping as a warm-up cardio
30 squats, 30 sit-ups, 12 push-ups. Repeat thrice.
Lay back for 2 minutes to cool things down
And that’s it. It’s not much for many of you, but it makes me push harder in the end. I consider it a good workout for my non-running muscles. The sole aspect of training is to better yourself to the best, and not to surpass anyone else.
