A very new and innovative concept from Polar - The Polar F55 with Keep U Fit (Cardio Vascular Fitness and Body Workout (Weights / Resistance workout) programs. The Polar F55 can prescribe a total body fitness program (CV and muscle toning) for the user. Alternatively; if required; just a Cardio Vascular program; or just a Resistance workout program. With the Keep U Fit program the watch may prescribe; for example; 3 x sessions - 1 x long; low-medium intensity; 1 x medium duration; medium intensity; 1 x hard and short. The watch will allow you to select which one of these 3 you perform; or just a free; personally controlled; exercise session. After 3 weeks of following the exercise program the unit will ask you to re-test your Fitness level and then recalculate your next three weeks program. It is an ongoing cycle of exercise; monitor; test; prescribe; exercise; monitor; test prescribe...... a great motivator. With the Body Workout program the watch prescribes a body toning program with 10 x exercise movements; see below for a selection of available movements. There are 17 different movements that the user can add or remove to this program at will. The maximum number of movements per workout is 14 and you can only use a movement once per workout (each movement can be repeated 1 - 3 times per set; see below for definition of "a set") The program does NOT allow the user to set more than 3 sets per movement. The program will select weights based on the users age; sex and weight. The user can overwrite these weights. The program will generally recommend between 8 - 12 repetitions per movement per set; the user can NOT change this setting. A SET ? = a number of repetitions per movement i.e. 10 x biceps curls repeated three times is 3 SETS of 10 REPETITIONS 17 x Available Movements -- used to make up a Workout (14 maximum per workout) Legs squats - lunges - calf raises  Chest bench press - flyes  Deltoids shoulder press - upri
