stimulus & strategy

Today's workout is a longer grunt-style effort. After two days of upper-body pulling and pushing, it's time for lower-body and midline work. Aim to complete a single round in 8 minutes or faster. Choose a medicine ball weight that only requires minimal rest breaks during the step-ups and run — hold the ball any way you like for both. If you have limited experience with the GHD, scale range of motion, and/or total volume. It may also be a good idea to consider weighted or unweighted sit-ups instead.
