No one wants to spend the first warm days of the year indoors. But if you jump into high-intensity activities before you have a solid base, you're at risk for injury. So start slow. Right now I'm doing 90 minutes a day on an indoor recumbent bike to prep for the bike racing and SUP racing seasons. If you've spent all winter watching football, heed the advice of my coach, Peaks Coaching Group's Hunter Allen: Pick a cardiovascular exercise you really enjoy and commit to seven consecutive days of doing it for at least 45 minutes. During the first 25 minutes, exercise at your "endurance" pace; increase the intensity during the last 20 minutes. The key is to not miss a day. After a week, you'll be well on your way.
