Change is all around us, and if we’re not recognizing that and changing with it, we’ll be in a bad position in no time.

It’s imminent in the business world, where previous giants Borders and Blockbuster (and a host of other companies) have declared bankruptcy because they couldn’t adapt to a changing marketplace.

As the son of a teacher (and now principal), I’ve watched how my mother has changed education with the introduction of the International Baccalaureate program at my old high school. This program engages students and makes them more aware of the world around them, as opposed to just having them stare at chalkboards and textbooks all the time.

The internet has changed the way shoppers shop, teachers teach, campaigners campaign, and ninjas “ninjer.”

Joking aside, change is something that applies to strength training programs as well. In addition to fluctuating training stress and rotating strength exercises, you have to be able to modify a program based on how you feel from day-to-day. When I was younger, I would just barrel through many training sessions even if I didn’t feel good – and I’m convinced that this stubbornness not only limited my progress a bit, but also led to some injuries along the way.

Nowadays, I’m older and wiser (and balder), and I listen to my body a lot more. Plus, I’m a much better coach than I was back then, so I know how to make substitutions in strength and conditioning programs to maintain a training effect. Pulled rectus femoris? Go to step-ups because they don’t extend the hip and flex the knee simultaneously (as you’d get with a lunge). Shoulder hurts? Try a feet-elevated push-up instead of a bench press, as elevating the feet increases serratus anterior activity and you can draw stability from the floor.

More generally, though, I’m honest with myself about where my life is right now. I’m 31 years old – which is definitely not 21 – and not competing in powerlifting anymore (although that doesn’t mean that I’m not still training hard on a daily basis). I have a wife, a dog, a house, a travel schedule, and a ton of stuff going on professionally with training athletes, writing, consulting, and lecturing. In short, there are a lot of competing demands.

What does this mean in the context of my strength training programs? Well, to be straight, the “highs” aren’t quite as high, and the lows are actually “lower.” Let me explain.

Take this training session, when I warmed up on trap bar deadlifts and felt pretty good, so made the decision to push the envelope a bit. I wound up pulling 700lbs.

As you can see, it came up surprisingly quickly. In years past, I probably would have jumped to 720 for another attempt, or drop back down to 630-650 for some additional singles at a weight over 90% of that day’s best lift. I might have even done some backoff sets of 3-4 reps at 600. Instead, I just called it there and moved on to my assistance work, as I was feeling a little banged up and wanted to make sure I still got plenty of quality work in over the course of the rest of my strength training session. That’s not to say either of these follow-up approaches would have been the wrong choice; they just weren’t the right choice for me on that day. The “high” wasn’t so high.

Likewise, when it comes to deloading, I wind up cutting back on things a bit more than I did in the past. In my e-book, The Art of the Deload, I outline ten different methods for deloading in strength and conditioning programs, and nowadays, I tend to go with the most conservative of the bunch.

Some might look at this piece as me telling people how to be soft and do less in their strength training programs. The way I see it, I’m just encouraging folks to train hard, but intelligently, listening to their bodies along the way. Along those same lines, what modifications have you made to your strength training programs as life has gotten busier and you’ve gotten older? Please post your comments below!
