There is little use if consistency is lacking. You must comprehend how the body functions because the human body is totally adaptable. Keeping this in mind, it feels like hell when you eventually work out for the first time in your life. Heck, you've experienced being close to death. But! What will occur if you keep hammering on that door? Your muscles start to deteriorate as they renew and grow stronger to meet the demands of your workouts. The pain is worthwhile, so keep going, and bam! It gradually gets better. You only need to show up and put in the work to be consistent; you don't need to be the smartest or fastest student.
