Workout and Brief thought

Nice solid workout today - and I can even document it.
40 minutes:

4x4x Overhead Squats - 135lbs -> 100 x over jump rope between sets
2x2x Overhead Squats - 145lbs -> 50 x over jp between sets
1x1 Overhead Squats - 155lbs -> 200x over jp

4x12x Leg Press - 360lbs
5x25 Hanging leg raise
4x12x seated shoulder press - 75lbs
4x12x lateral raise - 20lbs
2x30x shoulder rotation exercise - 5lbs

Here's the thought that struck me recently - given age, condition, and historical injuries - I'm likely not going to do super heavy back-squats again. I can do my bodyweight without serious impact to my spine, but anything beyond that...isn't happening without repercussions. Kinda made me sad since at one time I was able to properly and cleanly back-squat 575lbs. While not monstrous weight, I enjoyed being able to do it. This year is dedicated to flexibility, mobility and adaptability.
