But from a health perspective, moderate strength training is crucial for the elderly population.Intelligent technology has injected new vitality into outdoor fitness equipment, enabling it to not only have the function of fitness guidance, but also provide training plans according to individual needs. These smart devices not only record fitness data, but also enhance the fun of fitness while ensuring safety, thus meeting the diverse needs of users of different age groups for exercise intensity. It can be said that today's intelligent fitness equipment has truly achieved a perfect combination of whole population service and personalized exercise advice.Model making software: 3ds Max 2014 Rendering software: vray3.60.03 for 3dmax2014
