After a ton of research, the only thing that worked for me was bodyweight workouts and barbell training.
To drop my weight I followed bodyweight programs at home. 20 minute short sessions with squats, push ups, etc. Far more challenging than it sounds! You can see pics of how I dropped 20 lbs in this post:

Then I jumped onto barbell training, complemented with bodyweight sessions.
Starting Strength has been the best resource I've followed so far. For a small time investment a week, I've been progressing in technique and strength steadily over the last months.
The fitness field has been a huge motivation personally for me, which ultimately made me leave my previous startup and found http://8fit.com to help people like me follow that learning path.
