It's not the more the merrier, It's the smarter the better.
And in other words- stop adding Junk Volume to your workouts!
There is this myth that i keep hearing and seeing that the more you do the better.
3 hours workout, 2 workouts a day, 100 repetitions and no rest days.
Come on…
This is not contributing to your progress! Sometimes less is more.
Here are 3 examples:
Overtraining- Too many exercises and workouts per week + not enough rest. This will prevent you from recovering, increasing the risk of an injury and will cause Fatigue.
Too many classes / workouts with not enough resistance- honestly here you are just wasting your time. You can add those types of classes to your routine but try to put strength training as your main workout.
Poor technique- the biggest problem is that most likely you will not work fully and in a productive way on your target muscle. Focus on quality, not quantity.
