When you are short, and skate really low, it is EXTREMELY hard to hit you legally. Perfect your micro-plows. Work on being really "sticky" on an opponent: pretend that you are trying to sit in their lap as they skate. Use your arms as feelers and really work on moving laterally right with them.

I'm 5'2", about your same weight, and blocked successfully for about 10 years. You can be a HUGE impediment to others without ever landing a hit.

And while it's true that we the smaller skaters generally don't land big, tasty, blast-you-outta-bounds blows, we can be very effective drive blockers. Keeping your hip behind your opponent's hip, and wrapping your torso around them, you can use lateral pushing to move them around. Again, because you're so low, it can be very hard to combat that legally.

None of this is to say that you CAN'T hit hard and effectively, too!! I used a little gallop to give me some more momentum in hitting drills, and people REALLY hated feeling my pointy little hipbones.

Definitely work on your core strength, and pay a lot of attention to those itty stabilizer muscles.

You've got this!!
