I'm in my early fifties and am in pretty good shape except for my messed up shoulder, sore hip, and f'd up left ankle. Those were mostly caused by a lifetime of off road motorcycling and other contact sports.
I'm finding my body is responding well to the Texas method with a couple of minor mods. My goals were 5/4/3/2 wheels per side on deadlift/squat/bpress/press and can rep that now on squats and once for the bench press, with the other two close.Trying to stay ahead of my soon to be 16 year old son helps too.
I'm having only very minor pain issues at this point in my life. It's when I stop lifting that the pain and partial immobility returns, especially in my shoulder.
