You must give your cent percent during every single workout

Fact – You should try to be sincere and focus on your workout. But hey, wait! Not each and every gym session needs to be a high intensity or high voltage one. Feeling sore every day? That simply and pretty obviously means that you're pushing yourself too hard. "It's not a good idea to exercise at too high of an intensity too frequently—it limits recovery and can lead to overtraining," says exercise physiologist and trainer Pete McCall. To help your body guard against stress, you should turn on the ‘super-hard’ mode only twice or thrice a week.  

Important Points

• Enjoy your workout. Remember, the journey is more important than the destination. If you do your exercise sincerely, enjoying it at the same time, you will get the results faster than you think and feel good about it as well. But be tough on yourself not more than 2-3 times a week.
• Workout should be a workout, not a punishment. The moment you go hard more than twice or thrice a week, you start losing interest in your exercise. Hence, giving 100% effort during every workout is not mandatory; rather, it should be avoided.
