Want to boost fat-burning? Use a
stack of 200 to 300 mgs of caffeine
and up to 3 grams of L-Carnitine 30
minutes prior to your HIIT session
to encourage your body to burn
more fat.

For Performance

You don’t have to get stuck on a treadmill, or limit
what you do on it. Consider working stairs, hills,
and other apparatus into HIIT cardio to not only burn
fat, but bring out additional details in your physique.
Hamstrings and glutes benefit from stairs, and hills
(real or manufactured). Be sure to refrain from using
hills during low-intensity intervals as you rest.

>> Session Variety Is Crucial
