As someone who (in a past life) was an "elite athlete," my mind often thinks my body is capable of more than it actually is.
Well, it still is ... just less often and with a higher chance of hurting myself.
It's taken a lot of adjustments to find what routines work for me. They can't just be low-impact or good for me ... they have to be fun, and they have to allow me to improve, not just maintain.
I've found a couple of things that work for me, like the Carol AI Bike and HOTWORX.
Another one of my favorites is the X3 bar by Dr. John Jaquish. It's a metal bar that attaches to various bands and allows you to do variable resistance training. It's more efficient and effective than weights because, instead of using the same amount of force through the entire rep, you're able to do more weight where you're strongest and less weight where you're weakest.
He works with professional athletes, NBA teams, and more.
I shot a video with him about why X3's variable resistance is a better way to exercise. Check it out.
My son, Zach, is a holdout only because he prefers spending an hour in a gym. It's his meditation and his social hour all in one. I get it. I can't pretend I don't still enjoy going to the gym and lifting weights. But, I can recognize a lot of that is vanity and fun instead of prioritizing effectiveness and efficiency (getting more done in less time).
Taking a "Less is More" approach flies in the face of "No Pain, No Gain."
The X3 is portable; it doesn't take a long time to set up or use; and I feel stronger when I use it consistently. That means it is efficient and effective. Surprisingly, it is also fun.
The new X3 Force uses tracking & gamification to encourage use and progress. That is important because, with any of these tools, you still need to consider the Head, Heart, and Feet of the matter. It isn't enough to know what or how to do something. You have to want to do the thing. And then you have to actually do the thing.
I'm excited about this, because I think increasing longevity is a promising frontier, and I believe short effective workouts are fundamental to living healthier and longer.
Hope that helps.
