How many times for squat per week?
Is the barbell squat jump work?
I do squat 3 times a week.
depending on your goals and what kind of phase you're in, you could squat well over 3 times per week.. but in general, for strength gains using 'typical' programs, 2-3x/week.
barbell jump squat can be effective yes, 30% of 1RM, 5 x 3 etc.
