These are the points to achieve better results in my point of view:
1. Warm up before and after the workout mandatory.
2. If you want to do both cardio and Weight training in the same day,better to do Weight training first .
3. Outdoor jogging is best when compared to treadmill.
4. Some people may hit the gym to reduce belly fat ,But don't do the abdominal workouts everyday.Dont exceed more than 2 to 3 sessions in a week.
5. If you want to acheive 100% result,give equal importance to Workouts and Nutrition.
6. Try to take natural food instead of depending on the supplements.
7. If you are doing workouts without the help of any trainer,Always keep an eye on the result and change the workout style if you wont see the result.
8. Workout posture should be important.
9. Sleep properly.
10. Always compare the result of body composition, analyze every month.
