Here’s an insight from biology and anatomy that we can apply to any area of life and work.
You’re at the gym doing resistance training with free weights. One of the exercises in your routine is to work out your calves by standing upright while holding two dumbbells at your side. You rise up on your toes and then lower again. You’ve worked up to 2 sets of 20.
I’ve recently learned that the key to toning and building muscle tissue is that on your 2nd set, your last few reps need to push you to the point of muscle exhaustion. This is the point where it would be very uncomfortable to go any further.
