This was a killer! My upper thighs are on fire. Best exercise I’ve done so far. I’m not able to stand. My legs are very weak and the nerves to my legs I really don’t have any but when you are standing in going through the exercises, I’m trying to do them as I’m sitting and truly this was the hardest I’ve had so far like I said my size are on fire. It was awesome best one yet Darren thanks so much. I really appreciate it.
