30 minutes work out, 3 times per week. There are a lot of cardio
workout in youtube that you can follow. The
best one
for me is FitnessBlender channel. They teach exercises whilst tracking how many calories you burn. It's okay if you can't finish it all (30 mins) , It's fine if you only did 10 minutes, after your body gets into it, you can do that 30 mins like for the 5th week.
Avoid sweets, junk and processed foods.
To avoid them, replace sweets with fruits.
