Pam currently runs on a track an hour a day, three days a week. how can she increase the intensity of her runs? start running five days a week start running in hilly areas or trails switch to walking six miles each day add 20 minutes to each run

Ijust want the meaning to life (no wrong or right answers i just want your true opinion)
