Make sure you are splitting up your protein intake throughout the day. This allows your body to constantly be in the state of protein synthesis, building new muscle fibers.

Eating none in the morning and big chunks in the evening is not optimal for muscle gain and recovery. Note that your body can only properly make use of about 25 grams of protein in one sitting.

If you make a shake or meal that contains 40-50 grams, consider eating half of it later on. One sitting refers to about 1-2 hours. Otherise your body won’t properly absorb it and you risk putting strain on your kidneys.


Whey protein is a quality protein source and contains all the essential amino acids. It is also very digestible and absorbed by the body quickly.

Optimize Your Rest Day

Rest days are very important for building muscle. This is the time where they are getting stronger and preparing for the workouts that follow.

Get enough sleep on your rest days and every day for maximum muscle growth. 7 hours a sleep a night is required for your muscles to recover properly. Growth hormone release and protein synthesis occur while the body is asleep.

Get lots of water in to help fight muscle soreness. Water allows nutrients to flow into the muscles, helping them recover quicker.

Stretch or foam roll out any sore muscles. Foam rolling will break up fascia and release toxins from the muscles, reducing soreness. Read more about foam rolling here.

Stretching helps alleviate tight muscles which leads to a speedy recovery.

Remember to get your protein in! Note that your body doesn’t require as many carbohydrates on rest days. This is because carbs are used as energy for difficult workouts. This is why many people incorporate low carb days when they rest.

Rest days prevent you from overtraining which results in injury and burnout. If you feel that you are weaker and not having the best workouts, sometimes taking a day or two off is the best. You’ll notice an improvement once you step back in the gym.

How many rest days should you have in your training program?

Experts recommend two rest days per week for active recovery. It can be difficult for those invested in their fitness to take two rest days. Think of them as growth days rather than rest days. Understand how important it is to take days off so that your mucsles can rebuild.

Studies have shown that those training 4 or 5 days a week progress more than those training 6 or 7. If you are training hard enough, then this is plenty. See more information on rest days here.
