the pendant i used before for 2 weeks. my friend lend me to see whether it has effect or not.

i got positive result during 3PM-5PM working hour, usually i'll be tired and wanted to sleep. while using it i felt ok, no tiredness.

but i think it depends on the user-body.

okay here comes another question
should we be locking out our knees when we're doing squat?

Am doing front squat today,1 huge fella come to me,and ask me to wear belt for protection,and ask me not to squat heavily(yea that time i was struggling at 140 lbs+20kg olympic bar, front squat for 5 reps)
According to him,I am not supposed to lock knees when I am standing up,I should control the movement slowly and maintain the muscle tension there.

and he did pointed out I tend to 'bounce' when I am standing up,which is stressing more to the knees.it will hurts the ligament and I will be regret after 3-4 years.squat should not be too heavy as I am not competing ,why rushing ? yes I admit it,when I am standing up I tend to bounce so the lift will be easier.but I never realized thats a cheat form and could be potential harm to my knees.

Well,kinda speaking,he's much bigger than me and least years of experience,so now...I always think that squat should be go heavier,or i should follow to this guy advise? dont lock out,go slowly..

and my feel left knees knuckles cracking when I am doing front squat..which I recheck my form,its should be shoulder stance,foot pointing outwards,hips go downs,knees not over toes....it is not pain but feel weird....

There are not over than 5 people squating in the gym room,and only 1 people who doing deadlift,thats me ! none-of any instructor there,which I barely cant find a big bodybuilder and ask for the skill helps.

Someone enligthen me , I am confused,especially the knees cracking part,and I might not want to harm my knees,I know squat is way too important,but if I am doing it wrong end up this might be my last chapter of bodybuilding.I did googled,but too many version there ,confusing which 1 to follow.

I'll tell you why you can't go low enough. You're just trying to go too heavy. It's that simple really.

not sure if this helps, but instead of imagining yourself folding down, imagine getting your torso in between your legs.

FF Summit eh? & man, you sure can take on a lot of weight for your build. Good job on that.

As for form, squat with lower weights and you'll do better. You should prioritize working on depth first. I separate anterior and posterior chain work, so I go with the low bar squat and front squats. Don't really like high bar squats since they don't really work my hams and back.

Also, try breaking at the hips first like you're sitting back (but not too back till your knees go behind your toes). With a lower weight, that should help you reach enough depth.
