Absolutely! It is important however to make sure that you are doing it because you WANT to do it, and because it brings you joy.
If you feel like you need to do more exercise because it will bring you results quicker, or because of some sort of negative emotion like guilt or shame, then I would say no.
Contrary to what a lot of people believe, more exercise is not better. In fact it can be detrimental to your goal. This is due to subtle changes that can occur when we do too much and recover too little.
If you feel like you would genuinely like to do more workouts in a week, then feel free to send me a message and I'll be more than happy to add some in for you!
