Minka Kellys treadmill workout: 1 minute at 5.0, 1 minute at 5.5, 1 minute at 6.0, 1 minute at 6.5, 1 minute at 7.0, 1 minute at 7.5, 1 minute at 8.0, 2 minutes at 4.5 Repeat five times. Love this, did this last year when I was training for a 5K and I lost like 8lbs in one week, running this every two days. :) It really works! Great way to loose weight fast!
Another pinner said: This website is AMAZING. It is my workout bible, and best of all, its completely FREE. Tons of workout vids and plenty more to stave off ruts. Most of the routines are between 12-20 mins long and that's all you need.
