Lifting Weight but now... in 2D

This is my first time using Toon Boom. I created this guy, named Igor, just for fun, and I decide to try to do the same exercise that I did in 3D last time, but in 2D.

I found Toon Boom quite nice... except when I reached a point where Toon Boom decide to delete my keyframes and erase all my work... some kind of bug I think. It was a miracle that I recovered my drawings, and with those, I started setting the timing.

This is a sketch, and later I´ll start adding color, and pulling certain details.

Pulling Weight

My main problem with this animation is that I was going around, advancing little by little until I got desperate and I didn't enjoy it anymore. That, and that I've always had troubles synching the props between the IK and the FK, so there are some pops that are bothering me.
