Yup. The stretch is a killer when you pause in ATG. I also only do about 5 sets plus one set of unilateral work on my squat days. Ive worked in some smith machine pause squats with a high bar and nothing kills a quad like this. Unsure of the strength potential but I was in a hypertrophy phase so it worked in great.
I also really like [hate] lunges and I made the mistake of doing them following an ATG pause squat session... The soreness wouldn't go away even after a week, kind of threw off my usual workout routine. So now I don't even bother with anything else except squats. Makes for a fairly quick workout too, which I like.
Haven't tried the Smithmachine for squats in ages. I use it frequently for lunges though.
Is there a special gym's earphones... Without wire... And without having to take with me the device on my pocket. I'm so dependant with musicdou.
Google "Anker SoundBuds curve wireless headphone amazon". I've been using those for a while. They're cheap, comfortable, decent battery life and while I'm no expert on the subject, I find the sound to be pretty good. For the price, I don't regret buying them. The bluetooth connectivity can get a bit wonky at times, but it's nothing a turn off and on can't resolve.
There's definitely better products around, but I'm not the type to drop 100$+ on some earbuds.
