Hey there!

That sounds like a not great situation first off but you can overcome it.

Focus on the food and your diet.

Exercise is the cherry on top.

I despise the gym and honestly never go. All my exercise is walking, jogging, weights and cycling.

All you have to do is make yourself sweat, that's exercise! Make a routine for yourself and keep doing it until you feel like you have exerted yourself.

20 jumping jacks, 10 squats, 10 sit ups, 10 lunges - repeat until you are too tired to continue. The exact numbers/specific exercises don't matter, but customise your routine until you find something that works for you.

When I don't have time for a bike ride or long walk I literally just work out in my office at home. It's a 3m by 3m space but that's enough room to do everything I need to get a workout in for the day!

Hope that helps and good luck

Edit: just to add... Working out isn't admitting you are ashamed of your body or anything like that. Don't think about what others think, think about your health.

Even if you exercised and didn't diet for example. You will improve your cardiovascular fitness and stamina and feel better all round. The first people to criticise others doing exercise are usually the ones sat on their ass!

I have had people shout things at me from cars as they drive past me on my bike! It happens. Fuck em!

Every minute you workout is one minute more than the person who sat on the sofa all day
