As we said when we started this challenge, these are only numbers. They don't define us, but we would like to see some improvement.
"It just gives you an idea of where you are," says our personal trainer, Irene McCormick.
More importantly, in the end, it gives us an idea of how far we've come.
After about two months of working out - hard - and monitoring our food intake, Irene brings out the tape measure again. She measures our arms, waists, hips and thighs.
Here's a look at the before and after:
Erin's Measurements Before:
Erin Measurement's After:
Sonya Measurement's Before:
Sonya Measurement's After:
Erin's Body Fat Before: 18%
Erin's Body Fat After: 14%
Sonya's Body Fat Before: 29%
Sonya's Body Fat After: 27%
Our strength is measured by how long we can hold a plank. McCormick starts her stop-watch, "If you're fit you're going to be able to hold plank for more than a minute."
We both shatter our record.
Erin's Plank Before: 2:48
Erin's Plank After: 3:01
Sonya's Plank Before: 3:29
Sonya's Plank After: 4:14
The scale is another measure of progress, although McCormick says body fat and measurements are better indicators of fitness.
Erin Before: 125
Erin After: 118
Sonya Before: 153
Sonya After: 148
We credit our success to High Intensity Interval Training and logging our food. "Food is 80-percent of it," says Irene.
It hasn't always been easy, but it truly has been fun - and eye opening. All it takes is a little effort to see big results.
