1. Oh ok. cause I have a few friends who feel sore on their quads as well. Yet to feel any sharp pain.

2. No idea man. I find my pushing movements are very weak for some reason. Cant progress as fast as my Squat and Deadlift. Need to rest more in order to perform the intended reps. Noted on the rest until ready for the next set. Will try to increase my rest time for Deadlift to see whether there is any difference or not.

3. Nope. Dont plan to complete. More like for self satisfaction. I dont think my gym would allow chalk though. Have not seen anybody using chalk at where im training. Is there any bad effect using alternate grip long term?
