Combine 2 workouts

Hi everyone, I wanted to know if it was possible to do 2 training sessions since yesterday I missed training and today I would like to make up for it since I have more time available, is it recommended to do so? yesterday I had HIIT today ENDURANCE I wanted to include HIIT repetitions at the start of training and then continue with endurance what do you think? I accept advice, thanks

If you are not over doing it all the time, I see no problem with this. If you are tired or run down then maybe not the best idea.
