What does PM stand for?

What does HR stand for?

HR refers to the Heart Rate. The machine uses the heart rate or beats per minute (BPM) as a guide to track the specific rowing intensity. This metric can be measured with a heart rate calculator.

What does HRR stand for?

The term “HRR” refers to the Heart Rate Reserve. Also known as Karvonen Method, it is mainly used to determine heart rate zones for training objectives. The formula to calculate HRR is Maximum Heart Rate - Resting Heart Rate. 

What does HRM stand for?

HRM stands for Heart Rate Monitor. This device is required to record your Heart Rate (HR) every second. Ideally, an HRM must work with iOS (iPhones) and Android, display beats per minute (BPM) on PM5 and other brands, and override smartwatch heart rate monitor during a rowing workout. 

What does MHR stand for?

MHR in rowing refers to the Maximum Heart Rate. This numeric value indicates the highest number of beats per minute that a person’s heart can reach. As a rule of thumb, the formula to determine MHR is 220 - Age. Our Heart Rate Calculator uses 205.8 - (0.685 x Your Age) to determine the maximum heart rate at better accuracy.

What does LWT or HWT stand for?

LWT and HWT in rowing stand for Lightweight and Heavyweight. LWT is a category of rowing where limits are placed on the maximum bodyweight of competitors. 

Gender Heavyweight Lightweight
Men 165+ Lbs / 74.84+ kg 165 Lbs / 74.84 kg

What does DPS stand for?

What does SPI stand for?

SPI in rowing refers to the Stroke Power Index. It is a useful metric to boost your rowing journey. SPI is all about calculating load distribution. It is the ability to do a significant amount of work within a given time frame. 

What does LP stand for?

LP stands for the Low Pull. It is the fastest Split (time for 500m) that you can achieve i.e your maximum speed.

What does SPM / r20 stand for?

SPM is Strokes Per Minute. It is also known as “Rating.” This number is mainly displayed in the upper right corner of the Performance Monitor (in the example of Concept2). r20 refers to the 20 strokes per minute in which the flywheel takes more time to speed up the rowing machine.

What does TT stand for?

TT refers to Time Trial in rowing. This metric shows how fast you can cover a particular distance. For example, if a person sets a target of 2000m, the time trial is how fast he can row it to cover the distance.
