Plz tell me the difference except instruments. And what will be better
Well really either can be used successfully to get results. The instruments are probably the biggest thing that seperate them. Obviously there are instruments made for whatever plan you have, but there are also others who are striving for the same goal at a gym, but there are also people who have reached their goals and are intimidatingly bigger and more fit. If you have the money for a membership overall I'd say it's a good investment especially with friends, but if you want to save money and get potentialy the same results just use this app and others to exercise at home.
