1. VJB
2. NOivce plyos + bodyweights work great, but if you didn't train before, I suggest you do beginner plyos first, just like what I did last year, then move on to novice. But if you have good base, novice is fine.
3. I gained about 3-4 inches from beginner + bodyweight. I can't tell you how many I gains from novice + bodyweights coz I just stopped training because of my knees.
