When it comes to regular exercise, pain is something to be expected. It's not necessarily a bad thing... sometimes it's just muscle soreness or a little twinge. Hell... if exercise were fun and easy, everyone would do it.
But not all pain is good, either. Sometimes it's a signal of injury to come. Sometimes it's our body's way of screaming, "Slow down! I can't keep up this pace!"
The key, of course, is really being in tune with our bodies. Understanding each and every twinge. Knowing the difference between regular aches and dangerous pains.
Today's workout plan is a 3 mile run. I'll probably do some light stretching, too. Sometimes I think my twinges are because I lack flexibility. Stretching is often the first thing I skip if I'm pressed for time.
