Combining body training with cardio is the best way to go, be it fat loss or muscle gains. I know how difficult it is to keep records. Been there, done that. But believe me that will be worth your time. You'll be able to compare your current strength with your past records and you'll be amazed by your progress. Keep tracking :D
Thank you Rahul for your motivating comment!! I love this type of training and i am seeing results already!! :)
