Be patient
for sure... I see that you've done very well in your weightloss journey so keep up the great work...
Also make sure your diet is squeaky clean... As the saying goes "Abs are made in the kitchen" the cleaner your diet the better... You can not out exercise bad eating habits...
The title of the thread is ''HIIT with cardio and strength training exercises'', but I don't see any weight training in your exercise program ''jump rope/high knees/running in place '' is not considered weight training it is still cardio... Weight training would definitely be an asset to your workouts... Muscles help burn calories even at rest...
