There are many ways to fit exercise into your day-to-day life — no matter how busy you are. Here are a handful of strategies to try:

ANALYZE YOUR CURRENT ROUTINE
Start paying attention to how you live your day and you might notice you spend a lot of time scrolling Instagram, or that the time you thought you were spending on work is mostly eaten up by distractions. Once you identify exactly where your time is going, you can probably find spots to free up for exercise.

START SMALL
Committing to a workout doesn’t mean you need to take hours out of your day. You can even break your workout into smaller chunks to be done throughout the day if you can’t manage it all at once; don’t discount the effectiveness of exercising 10 minutes here and there.

HAVE A PLAN
Maximize your time in the gym (or at home) by planning your workout in advance — even if your plan is as simple as walking on the treadmill for 10 minutes and working through a few sets of dumbbell squats and chest presses.

WAKE UP EARLIER
Admittedly, waking up early to sweat it out may be a tough sell for many people, but if you’re a morning person, getting up earlier than usual could be a great way to fit in a workout, while starting your day off on a healthy note. If you’re having a tough time coaxing yourself out of bed, try waking up just 15 minutes earlier and doing a quick yoga or strength routine.

FIND ACCOUNTABILITY
Personal trainers, friends and family members can all provide support and help you stay accountable to your exercise routine — even on the craziest days. They may even be able to help you brainstorm ways to fit exercise into your busy schedule, and/or work out alongside you.

BE CREATIVE
Sometimes, life gets in the way of even the best-laid plans. But even if you have to bail on the group exercise class you signed up for, or that routine you got from your personal trainer is simply too long and involved to manage, you can still find ways to fit exercise into your day; something is better than nothing. So, take your dog for a walk, find a yoga routine or jump rope workout on YouTube, knock out bodyweight exercises like pushups and squats while you watch TV with your family, and/or do an abbreviated version of your planned workout.
