Question 1 - when do u take breaks during VJB? do u take breaks on novice pylometrics or just the weight training programs?

Question #2- For exercises like the side to side box jump it says one rep is each
ground contract. Does that mean everytime u touch the ground or
one time back and forth?

Question #3- Any idea how much is gainable from just doing novice pylos? Ive
done very little pylo in the past ( probably like 1 month of training)
and little strength training on my legs but i play ball quiet a bit. I
currently have like a 25 inch vertical.

PS: reason why im only doing pylos is because school is hard.
