In order to make progress in an exercise program,
you need to smartly push yourself out of your
comfort zone. If your exercise routine is always
comfortable, it’s likely not challenging you.
Walking the same route through the neighborhood or
performing the same strength-training program week
after week will eventually lose its impact.
On the positive side, exercise becoming easier means
you’ve progressed in your level of fitness.
For example, your heart rate won’t get as high
as you climb those hills, and the weights will start
to feel lighter and lighter.
