What does a HIIT workout look like? You could jog for two minutes, sprint for one minute, jog for two minutes, sprint for one minute. Or you could do a HIIT workout on a bike, or by running up stairs and then jogging back down. The key is that you go relatively all out for a short period of time, then recover by maintaining a moderate level of intensity, then go again.
The next time you train that muscle group, decrease the starting weight by 5-10 pounds. If any of the HIIT 100s exercises are new to you, you'll need to spend some time figuring out how much weight you can do for 10 reps. The week before you start the HIIT 100s program, work these exercises into your training to get a gauge on appropriate weights. When estimating your 10RM, be sure to do the HIIT exercise first for that muscle group.
And some of these factors can go pretty deep. Albers says that people often don’t realize how dramatically past experiences influence our relationships with ourselves and bodies. For example, having to clean your plate as a child, getting sweet treats to “cheer up” after a bad day at school, or being called “fat” when you were 8 years old all likely have an impact. “Comments about your body or being urged to lose weight by a parent can do emotional damage for the rest of your life,” Albers says. Unless you deal with these issues, “many people spin their wheels and don't know why they feel so stuck,” she says. For this reason, Langer often refers clients to psychologists who specialize in food issues, and she won’t work with those clients on the nutrition side of things until they’ve started to unpack these fundamental emotional factors. Understanding your relationship to food is an important step in trying to change it.
