Your high volume workouts may be paying off in the gym but hurting your performance in the bedroom. If you're doing more than 20-30 sets per workout and taking only 1 rest day a week, you may not be allowing your body to recover fully.
You experience "overtraining" when your body is in a constant state of breaking down. Symptoms of overtraining are fatigue, feeling sick, feeling groggy, inability to focus, and-you guessed it-low libido.
You could be doing too much cardio or weight training, but either way, when combined with a reduced calorie diet plan, the chances of overtraining are going to be that much higher.
Overtraining is one of the fastest ways to kill your libido as it destroys both your physical capacity and mental desire.
While some people can handle high volume workouts without feeling the impact, sometimes even if you aren't overtraining, your high volume workouts can severely deplete your muscle glycogen and leave you too exhausted to think about anything but resting.
After an intense workout, you may just need most of the day to recover. If so, make sure to get your Valentine's Day workout in during the morning or use Valentine's Day as a rest day.
If you are experiencing symptoms of overtraining, then you might need to take a couple days off before you're really in the mood. Taking some time away from the gym every so often to recharge your batteries and give the body rest is vital, but far too many people completely skip over this in their quest for results.
It's easy to think that taking time off will set you back in your progress, but in most instances, the opposite is true. After a full week away from the gym you'll find that you come back feeling fresh and ready to work hard. Plus, since the muscles have had a chance for full recovery, you'll often find you're stronger as well.
Remember that this applies to your diet too. If you've been dieting for 12 weeks or more, take a week off and bring your calories back up to maintenance level, which should be 15 calories per pound of body weight (or higher if you're very active). Doing this will reset your metabolism and make sure your body is functioning optimally.
