Add Tempo to Your Repetitions
This is a great way to change your routine and make an exercise more challenging.
I love to add tempo to most of my strength training exercises. It makes your muscles work for a longer period of time which will help to accelerate muscle growth and strength.
Next time you perform a strength training exercise, take four seconds to complete the lowering phase and four seconds to complete the lifting phase. Try to perform between 6-10 repetitions with a 4/0/4 tempo the next time you workout.
