First of all, congrats on your discipline to spend 1-2 hrs each day on drawing!
I haven't gone through Proko's figure drawing series, but I've had figure drawing classes and I assume they're similar. If you're having trouble with gesture drawing, try to focus on the line of action -- the line that runs through the body from the top of the head through the feet. You're basically drawing stick figures, trying to capture the pose. For 30 second gestures i usually end up with pages of stick figures, and for 2 minute gestures I have a bit more time to fill out the stick figures a bit.
Another tip for gesture drawing is to hold your pencil like this:
It may feel strange at first, but will keep your lines loose and flowing. It will help you in the long run.
If possible, you should see if there any life drawing classes or groups are held near you. Drawing with fellow artists is great support and inspiration, and you'll improve quickly.
You should definitely try to keep things enjoyable for yourself. Keep things fun and draw things that interest you, because there's no reason that you can't combine the study with fun. For instance, I'm trying to get better had drawing hands, so I've been trying to incorporate more hands in my drawings while still drawing things that I like. Keep things fun, but make sure you're challenging yourself.
I don't know if this any of this helped or was what you're looking for, but if you have any other questions, I'd be happy to try and answer them. Or if you want to throw up a drawing or two for a critique, I'd be happy to give my two cents.
