3. Count on cardio training
Aim to do 30 minutes of cardio, three to five days a week. For the best results, include some form of interval training-alternating bursts of intense activity with intervals of lighter activity.
“I tend to use a one-to-one work to rest ratio,” says Callaway. “For example, [I’ll do] a 30-second sprint followed by a 30 second jog or walk.”
You can vary the length and intensity of the intervals, starting at a speed and level that you feel comfortable with, she explains.
