Leg size seems to be holding up @ your age. Have you noticed any changes in your strength level and size?
great points nether i keep a keen eye on changes i see or ways to train around or even to maximize any boredom or 'just getting by'i don't fall into those easy ,i try to stay motivated in either strenght or pushing by super or tri sets at times ,age means something of course but i still approach it as i'm still into the 'routine'hard training forget 'age'
here was my leg workout today
leg press started i warmed up few plates a side there was a 25 on each side there already so i started throwing 45's over them my work sets were 5 plates and 25 per side,6 plates and 25 per side,7 and then i added a 25 on ;last set so total 16 plates were on the sled ,i repped 12/10/10/10/8
