Don’t let that sudden nip in the air put your workout plans into hibernation. Instead take your exercise routine inside. You’ll find a substitute for almost every outdoor exercise activity. If you love to swim outdoors during the summer, move your laps into an indoor pool. Do you treasure summer afternoons biking around the park? During autumn, maintain your fitness levels on a stationary bike until the weather warms up again. Moving into the gym can provide a great opportunity to mix up your training routine. Make use of the wide range of equipment in a gym and include weights as well as cardio into your plan.
