Yes, atleast we need to fit in a way that we can do all our activities on our own and doesn't need to have abs.

But our foods are highly carb and often lack protein sources which is one of the main reason for obesity and type 2 diabetes, we should consume less carbs and increase protein source whether as veggies or from meat (that's different politics

).
That is true, the usual food items we eat do carry a lot of carbs. I personally rely on Protein Shake to complete my protein intake.
These days though I am finding it hard to dedicate my time to the gym. I even fell sick and had a viral infection recently but I am good now.
Will be hitting the gym tomorrow again.
Oh yes, working out at home is definitely possible but we need a strong motivation to workout from home.
I have tried it and succeeded to some extent but honestly speaking, I prefer hitting the gym.
Calisthenic exercises like Pushup, situp, hollow body holds can be done without any equipment. Only pull ups require a pull up bar which you can order online as well.
These are good if done in the proper form. Form is of utmost importance or else the muscles dont get activated and you will not see any changes over the years.
But these calisthenics are the oldest form of free hand exercise and they are difficult to master, much better than going to a gym and getting into that subculture, I dont like it anyway.
Yes, Calisthenics are obviously better but to be honest, it needs a strong will power to start working out at home.
How do you guys start the workout at home ? I really procrastinate on that but I feel like working out at the gym once I am there.
