Abstract - Exercise helps us to lose weight and lowertherisk of some diseases. Physical exercise is important for maintaining weight, regulating the digestive system,building, and maintaining healthy bone density, muscle strength etc. Pushups are the most fundamental exercise type. Here to maintain ourselves in shape, pushups are the best motion exercise that require specific technique to avoid major injury. The smart band will support general exercise development for the same reason. The band "BE FIT SMART BAND" is a brand new, cutting edge, precise and user-friendly smart band that enables the user to exercise properly and to daily track their progress. In addition to measuring the user's BPM, this band forces them to perform pushups and pullups properly. The proposed system upholds accuracy and superior product. Future fitness tools are being provided via fundamental innovation.

Key Words: Pushes, Health, Exercise,Technology,SoC-System on Chip, Innovation, Smart band.

The proposed system presented is an upcoming innovative smart band which helps the user to perform pushupsneatlywithproper techniqueandpreventing the risk of muscle injury to the user. As it is focused to a particularexercise,itperformsonitsfullpotentialwhilethe user exercises. It measures the distance between the user andthegroundandwhenasatisfactorydistanceisachieved itgeneratesacountofpushupsperformed.Also,itmeasures the speed of the user while exercising to maintain a track recordofhis/herexerciseconsistency.Unlikeothersmart bands,itiseasytouse.Itsperformancespeaksmorethanits features.[2]
