Lose fat, gain muscle help me

Hello! Check in youtube for videos from Jillian Michaels. Ripped in 30, Yoga Meltdown, Shred it with weights... They usually come on DVDs, but people ripped those and posted them.
Jillian does routines with hand weights or kettlebells, but all of them can be done with water bottles (filled, of course). There are many demanding body weight exercises, but she has one of her girls show modifications, so you can work your way up to the difficult moves. Depending on the size weights you use, there is plenty of resistance to tone your muscles. You won't need a lot of space to do the workouts, either. The first few times, I was coughing out my lungs. You'll be torching some fat, for sure!
I started out with 2x 5 lbs dumbbells, one 8 lbs kettlebell, and a yoga mat that I got cheap at Walmart. I since graduated to 10 lbs dumbbells and a 15 lbs kettlebell.
Have fun!

Look up the following programs:

You are your own gym
Convict Conditioning.

These are both body weight based programs. If you have no access to weights I'd go this route.

These are excellent. I also loved NerdFitness.com's beginner body weight strength training. It put me on the road to lifting heavy.

What about adding some body weight exercises in to add strength routines to your cardio sessions? Google has thousands.

^ yes.
and when you are 'done', comfortable/over with the body weight exercises, you can get a resistance band... cheap, and superb!
