debjh,
I wouldn't be so quick to stop machines just yet. Machines are excellent tools for certain situations. When starting a weight training routine, building strength around a weakned joint, or learning a new exercise.
Adding more cardio to your program is probably not the answer to reducing your body fat levels. You'll probably be better off focusing on creating a kick butt nutrition program, followed by a great strength training routine and then supplementing with cardio.
Also, here are 5 of my favorite fat loss tips. Maybe they'll help you get started:
1) Eat 5-6 small meals throughout the day. Each meal should be 2-3 hours apart. Each meal should contain one protein and one carb. The first meal should be eaten within an hour after waking.
2) Drink a cup of water at each meal.
3) Rest properly. This means taking at least 48 hours between strength training the same muscles, and it also means getting at least 7-8 hours of sleep per night. Lastly, it means taking 1-2 days off from exercising per week.
4) Cardio. This should be done at different intensity levels and different session lengths. Consider doing a low intensity/long session, a high intensity/short session and a few medium intensity/medium length sessions.
5) Strength Training. Strength train each muscle 1-3 times per week. You should lift a proper weight and perform the proper amount of sets/reps for your strength training method. If you need more guidance or exercise ideas you can head over
All of the above things combined will result in fat loss. Best of luck to you!
