A belt-mounted movement sensor system apparatus has a flexible belt shaped to be worn around the midsection of the user. The system has an array of accelerometers disposed on or within the flexible belt to physically associate with positions on the midsection of the user. Each array of accelerometers has a sample rate that can be configured for sensing body movement during a movement activity. A power source and a data collection system are operably connected to the array of accelerometers. The data collection system has a means for receiving data from the array of accelerometers and processing that data into a storable format.
