I am 90kg and 5'6 and I am trying to lose weight
I have been trying to lose weight for 2 -3 years, and every time I always gave up after the first or second week, just rarely did I manage to lose weight I would give up and gain double the weight that I lost. Every time I start a diet I stop doing it after 3 days. I don't have motivation so I need to learn how to have discipline, instead of always giving up and giving myself reasons why I gave up. For diet, I am going to stop eating snacks and junk food, and it 1 - 2 times a day instead of the proper 3 times a day meal, for that since I don't get the discipline to stop eating I am going to put all my snacks in a box or give them away. I really hope I have the discipline for this, I am going to start going to the gym with 3 of my friends 3 times a week and I need to know what cardio workouts should I learn and what gym workouts I should do to lose weight.
My plan is for the workout anytime I go to the gym:
Stretch: 5 min
Cardio: 10 - 20 minutes
Treadmill: 20 - 30 minutes
Actual Gym workout: 30 - 40 minutes
Bike: 10 minutes
The gym workouts, I don't know what workouts I am actually going to do, because I am going to the gym 3 days a week, every Tuesday, Wednesday and Thursday. And I don't know if I need to separate which days I work on arms and all that. And for the rest of the days like Monday, Fridays, Saturdays and Sundays no jumping because I will be at home, and when I am in school I will try to get as many walks in as possible and next year join the sports team. I just need discipline and a routine, and I feel like having someone supporting me and checking up on me will give me the motivation and discipline I need. I don't know what to do, and I just need advice, I get embarrassed easily and the only reason why I am going to the gym with friends was that they asked me.
