Did it a couple of years ago,1 set of 50 reps on a basic exercise for each bodypart and for 6 days a week,took a couple of weeks for the cardio to get better and i can honestly say my arms looked the biggest they have ever looked.After about a month i started getting sore hips from squatting every day so i would squat one day and miss the next.Doing 50 reps on squats is no fun but once the cardio gets better it was fine.Its something i always go back to at least once a year to give the joints some rest.
I moved from high (high) weight, low rep and relatively low volume (maybe 15-20 sets per workout) to super high volume over time (depending on workout, 40-140 sets of 10-40 reps) - it takes a while to get the cardio up to scratch, but once you do, you're like a kid with ADHD and can't rest between sets, keep strength at a high level and have an ability to reduce rest between sets and push high rep sets to a point that is incomprehensible to low rep lifters.
It was great for my joints til lately. Think I have adapted too much, or am overtraining, but it gave me great results.
