Fit At 40+ with James Crossley

A dynamic warm-up is essential before any workout, especially when our bodies get that little bit older.

In this part of the series, we're going to work the core, which is very, very important to help prevent back pain.

If we do HIIT, we're cranking up the metabolism so you can be burning calories for up to 36 hours after the workout.

This workout is designed so we're doing an upper body movement, a lower body movement, followed by spiking the heart rate with active rest.

We're going to slow things right down, working the lower back.

The hard work is done. Now we're onto the cool down, which is extremely important.
