I went cardio heavy with stairmaster and treadmill. Nothing fancy; just burning fat and sweating. I did a variation of this, HIIT and weights 4 times/week.
I also employed a strict diet of rice, grains, veggies and lean proteins with lots of water and fruits and vegetables as a snack. I had to control what was going into my body as well. The goal was a calorie deficit and to do this for 4-5 days out of the week.
I accomplished losing the 3 pounds this way with a plan of switching it out and around. 4-5 hours per week in the gym and clean eating for the same number of days made that happen.
