Get Your Rest
If you think the lack of sleep is not hurting you and your training session, think again. You need to wake up. When you get enough sleep (less than 10 hours), you have a decrease in energy expenditure during weight training and cardio or aerobic exercise. This makes you sluggish and you do not get the most out of your workout session. Getting less sleep also tends to exhaust you sooner. This exhaustion can cause you to cut your workout short or skip it all together.
Think about this – being sleep deprived for only three days can make you significantly less powerful and more easily fatigued. Some days you are not able to get 10 hours of sleep a night, so at least shoot for four or more. The standard eight-hour sleep recommendation is a good target.
