Right on, thanks.

That's the key part. Leg blasters take a lot out of you. If you are lifting/running/biking a lot and add leg blasters you'll likely have to back off whatever else you're doing. But if you keep up your regular exercise and some split jumps and maybe squat jumps on tired legs you get a similar benefit without having to modify your routine as much.
Yeah, they destroy me when I start doing them every year, but I get used to them surprisingly fast. I’ll have to learn about split jumps. Have been out of the realm of organized training for long enough that I don’t remember what anything’s called anymore.
Edit: oh.. are split jumps the same as the lunge jumps that are part of a leg blaster set?

Gotcha. I’m not a PT, first of all, so take this for what’s it’s worth. The absence of specific pain spots or known conditions, along with your description, makes this seem like general deterioration and pain.
Assuming that:
The older you get, the more you atrophy muscles you don’t specifically work. Over time you get slight muscle imbalances and start to change your movements to accommodate those. That puts less performance requirements on those slightly weaker muscles, which in turn unbalances them even more and they can get amazingly week at a relatively young age. Pretty soon you aren’t squatting the same way (instead bending from your waist) and your knees get week. On top of that you sound like you do a bunch of straight ahead exercises (biking, running) which most of the time overdevelops the outside quad muscles and underworks the inside ones. And your glutes stop firing as well because you rarely do a full squat. So all that needs to be fixed.
First, the macro exercises. Real squats, with weight. Start easy but over some weeks build up to real weight with 5-8 reps sets. Do a bunch of squat forms (heels up, goblet, front) to build all the muscles, but mostly back squats. Use the right form. This will help rebuild your glutes and inner quads.
Deadlifts. Same program as squats. Use the right form and do a few variations. This will work your glutes and hammies and help protect your knees.
Hip thrusts and calf raises. Again, build the muscles around your knees to protect them.
Smaller moves: Single leg balance ball body weight squats. High reps. Like 14-16. This builds up all the stuff around the knee and helps teach the muscles to fire quickly for stabilization. 3 reps each leg, alternating.
Lunges, in all forms, for strength and stabilization.
The idea is that, right now, lifting your body is at the limit of what your knees can do. Strengthening them so that they can easily lift much more than that takes them out of a stress condition for your normal activities. Most people over, say, 30-35 (or younger) who haven’t done this kind of lifting much are shocked when the get in a gym and see how weak they actually are for these moves.
I also believe in glucosamine/condroitin supplements. They helped me. Science seems to indicate they help with joint pain and health but still some disagreement there. Your mileage may vary.
Hope this helps.
