Pushing myself

jbspangs

7 weeks ago, my weight started out at 258 lbs. I've since lost roughly 21-22 lbs and I'm feeling great.

I cannot afford a gym right now... And, I don't really have a support system to help me on my journey (aside from this site!)
I've been working out at home with P90x/Insanity (with some occasional Zumba to spice it up a bit)
The problem is... I'm not working to my full potential. I'm maybe at 70% at all times.
I don't know how to get myself to go for that extra mile... Any suggestions?
