The more we learn about fitness, the more fitness elements we need to keep track of, including workout routines, caloric intake, conversion rates, body-fat percentages, vitamin needs, metabolic rates, and heart rates. The latter just became easier with Suunto’s new M-Series heart rate monitors.

The new monitors, which look like regular watches—and can be worn as such—but provide a slew of additional information in an easy-to-use set-up, telling users when to train, how long to train for and how hard to train. Users also will be able to upload workouts and share fitness tips with others on, a new online sports community powered by Suunto.

The M-series comes in four models:

Suunto M1: introductory level; real-time training intensity guidance; heart rate and calories burned; automatically switches between three different heart rate zones for personal exercise targets; comfortable heart rate belt compatible with most gym cardio equipment.

Suunto M2: all the features of the M1 but with the additional Suunto Dual Comfort Belt  (compatible with gym cardio equipment) and Suunto Fitness Solution.

Suunto M4: start-up fitness test; three personal targets to choose from; real-time guidance during workout; displays exercise program for next seven days; Dual Comfort Belt; can upload data to with optional Suunto Movestick.

Suunto M5: all the features of the M4 but can also download any training program from; displays recovery time recommendation after exercise; tracks speed and distance (with optional Suunto Foot, Bike and GPS Pods).

In addition to program options, suggested workouts, and mid-workout advice, each model also offers nine language options: English, German, Italian, Spanish, French, Portuguese, Swedish, Finnish, and Dutch; color choices include black, pink, fuchsia, turquoise, silver, and gold. Prices start from $129.
