"Fitness trackers are incredibly personal, just like your workout gear you wear on your body day in and day out," Cohen, ELI Performer at Life Time Athletic Club, told "Good Morning America."

"I like to make sure it's comfortable, fits my lifestyle and workout, and of course attractive. No matter what your needs are there's always a sophisticated tool that can help you optimize your workouts or even just jump-start your routine."

Gilbert, a Barry's instructor and the founder of CG Coaching, said, "I find that having accurate data is the best way to know if you're moving in a positive direction without guessing."

"I love using heart rate monitors, as well as step and fitness trackers for all of my clients," Gilbert added.

Best fitness tracker for those with an iPhone

"I love the Apple Watch as it is the best fitness tracker for people who have an iPhone -- plus it connects to all Technogym equipment," Cohen said. "I'm able to constantly track my progress by connecting directly to the equipment -- I know that people tend to hold on to their Apple watches, but the newest model S9 has the new S9 chip, which improves battery life and privacy for your sensitive medical data."

Cohen, who teaches around 20 group fitness classes a week, added, "Even on my off days, I love to keep track of my workouts, sleep and recovery -- it is not only important but fun!"

"I think the Fitbit Blaze is a fantastic starting point that gives you digestible updates to know where you are at while working out," Gilbert said. "The Blaze has a sleek design with an easy removable head for charging. This tracker is great for someone just starting out or looking for a lower-budget item."

"WHOOP is a great package for serious athletes who are looking for an edge in their sport," Cohen explained. "WHOOP only captures the biometric data shown to have the most meaningful impact on your health. No other wearable gives you a more comprehensive look at your body's key performance data, and helps you understand what to do with it."

Best for tracking sleep

"Sleep is vital for an athlete, so being able to closely monitor how much sleep I'm getting while being so active has been a lifesaver to unlocking my true potential," Cohen said.

Gilbert recommended the Polar Vantage Smartwatch "for tracking your heart rate variability and your sleep."

"I've been using it for the past few months ... I can now know what affects my sleep in positive and negative ways," Gilbert said.

"My favorite tracker has always been the Garmin Forerunner 935. As an endurance athlete, the battery life and simplicity of this watch have been a huge pro for my training," Gilbert said.

Reviewers say the Garmin Forerunner 935 can function up to 10 days on a single charge. The tracker can also spend up to 30 hours in GPS mode to track your longer runs.

Best heart rate monitor

"Even though I love smart watches, in reality, a heart rate monitor on your wrist is far less accurate than a heart rate monitor worn across the chest. I have used monitors from Polar and Garmin, and enjoy them both ... the accuracy is always way closer to reality than a smartwatch will be," Gilbert said.
