Hey guys, quick question for you all. How long is my heart rate typically supposed to stay rapid after training? I train pretty intense and lately I have been noticing my HR will stay between 113 to 120 2 to 3 hours after training. Is this a problem? My other question is about shin splints. I have been sprinting on the treadmill and on the track and my endurance is great but it seems my shins give out before anything else. I stretch for 15 minutes before my workouts but my shins still give in on me. Does anyone have any techniques or stretches I can try?
