71 pounds? That is awesome.
I work out at the gym three days a week. Cardio, lift, cardio. This is my third year back doing it.
What I finally woke to is my diet. I started that last July. I won't say I diet anymore. I will say I have made a lifestyle change and eat right now. That is where a lot of people fail; diet, lose weight, go back to the "normal" eating habit, gain weight, diet, lose weight.
47 pounds down at this point with maybe another 10-15 to go.
