I love training hard and waking the next day to check out the soreness in the muscles. My first workouts with weights over 20 years ago produced intense and exquisite soreness the next day and over the years I have continued to experience that soreness and often use it as a gauge to indicate that I've been working hard - my pecs are sore: I must have trained effectively etc.
However, I've been thinking more about this recently. How useful in real life is such soreness? If a training session leaves you exhausted immediately after it and almost crippled with soreness the next day, is that a practical or useful way of training for everyday life?
I want my training to enhance my life. To make me fit for whatever challenges are going to come at me in those days. I might need to sprint for a bus, to sprint away from a fight or to defend myself in some way. If my ability to perform is limited because of my previous day's training then is there a problem?
Hard and intense training works and I enjoy pushing myself to the limit. But there is a balance.
I want to train hard enough to improve ....... but not so hard that I am debilitated and handicapped. Train hard but not so much that - paradoxically - I become weak.......
