Day 12 21-Day Jumpstart Fitness Challenge.

It's time to check our progress. Look back at the notes you took on Day 1. Our goal today is to increase the weights for as many exercises as possible. A good rule of thumb when lifting heavier is to aim for a 10% increase in the amount of weight used. Some exercises will be more challenging to progress than others.

Have several sets of dumbbells available to help you find that sweet spot of 'not too heavy, not too light'.

Tools: 3-4 sets of moderate to heavy dumbbells
