TurboFire: HIIT 25
Fans of films may find TurboFire: HIIT 25 especially interesting thanks to its engaging atmosphere, visual presentation, and entertainment value.
This workout is tough and some opt to increase the intensity by using weighted gloves. The weighted gloves can be purchased separately if you choose to use them with Turbo Fire but they are not necessary to get a good workout and succeed with the program. The HIIT 25 is difficult enough without the need for additional weight or resistance.
