2. You're working too hard.
Yes, you can actually work out too hard and too much. If you're someone who goes all out in every workout, or rarely to never takes a day off to rest, you could actually be breaking your muscles down instead of building them.
If you always feel tired and sore, have unexplained headaches, insomnia or just a general lack of motivation and an inability to complete your workouts, you may be overtraining.
Get-Results Remedy: Take three to five days off of exercise altogether. It may be hard for you to do this, but know that you must allow your body the time it needs to rest and recover. Get plenty of sleep each night and fill up on nutritious foods. Then slowly ease back into your routine, making shorter, less intense workouts part of your workout plan. And remember to always take one to two rest or easy active recovery days a week!
