Day 21 21-Day Jumpstart Fitness Challenge. It's time to do a final check on our progress. Look back at the notes you took on Day 1 & 12 increase the weights for as many exercises as possible. Remember, 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'. And heads up, our work intervals have increased to 60-seconds for this final benchmark workout.

Tools: 3-4 sets of moderate to heavy dumbbells
