# Heavy for Power and Longevity: How to Define It

> Learn how to define 'heavy' lifting for power and longevity with low-rep, high-intensity strength training to preserve muscle, bone, and overall function.

## How should 'heavy' be defined if the goal is power and longevity rather than muscle size?

“Heavy” is best defined by effort, not by a specific number on the dumbbell.

### How to define “heavy” for power and longevity

Here at Alloy, we use the definition Dr. Vonda Wright teaches: for your major compound lifts, *heavy* is a load you can lift **4 reps per set, for 4 sets**, where rep 4 is hard and you feel like you *might* be able to grind out **one more rep**, but another after that would get sketchy and your form would likely break down. That’s the point where the weight is heavy *for you*.

So if you can do 15 reps easily, it isn’t heavy enough for the “power and longevity” goal she’s talking about.

### What this looks like in real life

Dr. Wright’s example is that she can biceps curl 15 lb “forever,” but 25 lb is something she can only do about four times. That 25 lb is “heavy” for her in that movement, even if it might be light for someone else.

Because it’s individual, you usually find it by experimenting safely, moving up in small jumps until you land on a weight that matches that 4-rep feeling.

### A couple safety notes that matter

If you have osteopenia or osteoporosis, Dr. Wright’s guidance is that you still can, and should, lift heavy, but you want to build up progressively and keep form tight.
