The new Gear Sport will automatically track all the wearer's activity, continuously monitor heart rate and suggest simple exercises when users remain stationary for long periods. Samsung announced each device with its own focus on fitness, while some even feature sleep tracking and nutrition monitoring.
Samsung has not confirmed pricing for the Gear Fit2 Pro, although it has been tipped to come in at $199 or £199.
The Gear Sport is positioned as more of a smartwatch designed for active lifestyles.
While the Samsung Gear S3 Frontier is still relatively new, for those who want an even sportier approach with a minimal feel there's the Gear Sport, a smartwatch based on Samsung's Tizen platform that features a 1.2 inch circular Super AMOLED display with a 360x360 320ppi resolution.
"Samsung's innovation is inspired by consumers and created to make an immediate difference", said David Lowes, Chief Marketing Officer for Samsung Electronics Europe.
Samsung also announced several new home appliance products, including its new QuickDrive washing machine, which the firm claims can halve laundry times.

With millions of Australians into swimming Samsung Australia could have a big victor on their hands with the release of a brand-new swim tracking app in partnership with Speedo.
Away from fitness, these buds are also Bixby-friendly so you can tap and hold one earbud to use your voice to control your music. Some new fitness apps will be available with the Gear Sport, as well, such as a new Speedo app for tracking swimming and an improved Under Armour app for tracking calories. Samsung Gear Sport is powered by a dual core processor. It's got the same compatibility as the Gear Sport for Android and iOS devices and comes in black or red.
One of the biggest improvements coming to the Gear Sport and Gear Fit2 Pro is in the form of improved water resistance up to 5ATM (50 meters).
Under the hood the Samsung Gear Sport packs in a Snapdragon 2100 chipset and 768MB of RAM, while there's 4GB of storage as well.
Meanwhile, the Gear Fit2 Pro now has Global Positioning System built in, making it a great fitness tracker for tracking your runs and bike rides, without needing to bring your smartphone with you.
The charging case is smaller than before, supports quick charging and you can get a full charge of it (total capacity of 340 mAh). It's smaller than the Gear S3, too, which is nice for anyone that thought Samsung's last smartwatch was a little too bulky. And because runners may be into these, Samsung added a Running Coach mode that gives you real-time, in-ear status updates as you're working out. Naturally you'll need to have your phone with you for this to work.
