you'll definitely loose a lot of water weight, but what do you feel about high intensity interval training (HIIT) you can customize to your liking and change it up, search it on google and you will find different routines from different people, I started doing it about 2 months ago it really boosted my cardio, what i do now is 20 second sprint at 100% and then jog for 2 minutes then sprint again 20 seconds all out do this for about 20 minutes. just change up the times if you find its getting easy.
