That’s quite a bit of info to take in as a beginner. i’d say start small, and don’t be afraid to experiment (even if you lose). Start by learning how to counter lifts in some more basic ways, the rest will come naturally as long as you don’t stop experimenting.

For now, perhaps focus on using your pecs, elbows and wrists to counter lifts. Extending pecs and contracting elbows and wrists brings you closer to them, denying the lift somewhat. Bare in mind this is a somewhat nooby way to counter a lift, but good to learn with.

If you need any help shoot me a pm.
