agreed - even holding 50 lbs weights now in each hand I am doing high reps. Slowly adding more reps and my legs and glutes are growing. more than anything else, I can run up stairs, little job, walk my dogs for a few miles and not be in pain and limping.For older guys I believe that small amount of GH helps.Nothing wrong with high rep squats,plenty of speed skaters have used high reps up to 150,even 300.
I am sure the GH helped, but I am also very confident the peps did the most as I made the most improvements when I added in the new peps.
I will update in a few days on how the progress is going.
