Absolutely none. I tore all muscles in my right groin off the bone late summer, black and blue from hip to heel. Shoulders were rebuilt years ago and right one failed while lifting in March and was still giving me trouble then got MRI for neck and it showed 'DEGENERATION'.
Well now I have some REGENERATION. Lifting solid, heavier without more parts failing and will gently walk it up from here.
Spending a lot, have chance to buy Chinese cheep but its ILLEGAL so paying a lot and plan to keep paying for it.
Zero sides, other morning wood
