2. FITNESS
TRACKERS
Wrist-basedtrackerscapture
all sorts of biometrics: heart
rate, GPS, step counters,
accelerometers.
BASIC
MOVEMENTS
According to the fitness
experts surveyed in the
ACSM’s annual fitness
trends poll, bodyweight
training is making a
comeback to more basic
movements: pushups,
situps, pullups.
SPORT TRENDS
Taking care of our body is becoming more than a trend nowadays: people want to monitor what they
eat, how many hours they sleep, how many time they spend exercizing and the quality of their workout
WEARABLE
DEVICE
Worldwide sales of fitness
wearable device went up
163 percent in 2015 over
2014 and is expected to
keep climbing, according
to the International Data
Corporation investigation.
American College of Sport
Medicine, maximum world
authority in the field of
fitness, indicate the hi-
tech wearable devices
as the main trend in 2016.

3. QUICK &
CONVENIENT
HIIT workouts can be done
anywhere by anyone: at
home, in an hotel room,
in a park, at a gym, etc. It
doesn’t need so much time
for exercise, 10 minute are
enough for good results.
HIIT
In the rankings of the top 40 fitness trends, behind the sport devices .
( All datas from an American College of Sports Medicine )
WHAT IS
HIIT, or high-intensity
intervaltraining,isatraining
technique in which you
give all-out, one hundred
percent effort through
quick, intense bursts
of exercise, followed by
short recovery periods.
NO
EQUIPMENT
HIIT workouts generally use
only the body weight, since
the focus is on giving the
best while performing.

4. HIIT Me
The High Intensive Interval Training band indicate the timing of exercises
through vibrations, allowing you to give your best at each workout session.

5. HIIT Me
FEATURES
VIBRATION AS
FEEDBACK
Different patterns of vibrations
differentiate work periods from
rest periods, and the start and
end of each one including
those of the workout session.
INTERVAL
FUNCTION
2 preset work/rest interval
functions controlled by a
button. The green light of a
LED indicate easy workout
program and the red one
hard workout program.
USER
FRIENDLY
Easy to use, texture of the
strap makes it transpiring
and flexible, simple snap for
quick removal.

FINAL DISCUSSION
PRO CONS
COMMON
WRISTBAND
HIIT Me
• Emit too much intense sounds or feedbacks,
which may cause unconfortable feelings,
or too little intense ones which may not be
perceived.
• The user must interact with the device
touchscreen during training, or with the
smarphone before / after
• Capture all sorts of biometrics and
movements datas, from heart-rate to
step counters.
• The smartphone application converts
all the datas to graphical interesting
outputs
• No touchscreen or smartphone
interaction during training
• No waste of time to start and stop the
workout program during training
• Bright and vibration feedbacks
immediately perceived by the user
during the workout, to scan time intervals
and focus on exercises
• No bothering for people around the user
• SportSmartBand for everyone ( IoT, DiY )
• No customization of work/rest intervals
• Prototype looking / dimensions
• Price / function relation

47. HIIT Me
STRENGT POINTS
• We designed the HIIT Me band to optimize the fitness exercises that the user
can do and freely choose, accordingly to his/her needs.
• No screen because the most important thing is that the user does not interact
with an electronical device or smartphone during training, focusing just on
the execution of the exercises.
• Vibration as feedback because the user has to feel interval time on their
own skin, without bothering other people.

48. HIIT Me
FUTURE DEVELOPMENTS
• both preset work/rest periods coincide with the most used intervals for the
execution of this sport practice to get results; they can be utilized to make
any kind of exercize more efficent; thinking to more feedbacks and more
interaction modes, the device could me more and more efficent.
• if the device could be exploited in a modular way, from the material and the
programming side, it could give more sparks as a SmartBand project.
