Muscle rounds are soul destroying if you're not in awesome shape is my conclusion!
Last time I did these I was lighter and leaner talking low 200's at a true 8%.
Now I am over 220lb at a true 10% and I had to end a set early yesterday as I honestly thought I may keel over and die

Now yes it's nearly a 100 degrees in NC atm but my AC is set at 70 so you would think it's doable but it's not!
Now I am going to have to bring a portable fan around the gym with me and perhaps a bucket of ice to plunge my head into after sets so I don't feel panicky as fuck after sets.
I swear it took me 10 minutes to calm down after a muscle round of smith squats today.
It just felt like I had no air flow and I couldn't get enough oxygen in!
Perhaps those little oxygen bottles that was all the rage a year or two ago would help?
Srsly I consider my self in decent cardiovascular shape so I have no idea how any one who is not in tip top shape should get through these!
Using a really tough weight for 24 reps is not doing it right....
You need to pick a weight where you fail after 3-5 mini sets of 4 and then drop enough to finish off all 6 sets of 4.
Once your strength level is decently high this is insane for any thigh compound exercise.
Doing more than one of these atm is totally out of the question and possibly asking for a heart attack
