This workout is for those who like it hot and are not afraid to go an extra mile for that extra burn. Slightly longer than a traditional DAREBEE HIIT circuit this routine is here to add some spice to your day. To get the most out of your workout keep the plank during the plank to push-up transition and all the way through the final plank sequence. The calf raises are not there for you to rest, make sure you go up and down as fast as can - it's HIIT after all! Keep your arms up during bicep extensions so your elbows point forward for all 40 seconds each time. If you feel the burn, your are on the right track.
