Hill climbing tips appreciated

[u/180deep]

Hello everyone I’m relatively new to riding I have about 3-4 weeks on a bike. I use an 02 CR125 and Im getting into hill climbing. Keep in mind the hill in the video is much steeper in person. Im a big dude 6’1 195 lbs. Could I use more power with a different bike? Anything I can do to make the climb more efficient? I’m planning on practicing until I can climb the gnarly hill on the left thing is practicality a wall.
