This seems to be the mostly asked question in this situation, but honestly telling you actually can keep your weight in check without Gym or fitness centers, yes yes you heard me correct, the basic mantra of keeping weight at bay is calorie deficit and regular exercise ,now I understand we all are not fortunate enough to have a gym setup at home but yes your bodyweight is enough to do the trick , you can start HIIT training at home ,if you have resistance bands you can use them as well , you can search in youtube with the aforesaid names of exercise and you wil get a lot of help, go ahead and give it a try , all the best 👍

Yes you are correct it's the lifestyle change that's taking a toll on our health , less activity, or sitting in a same posture for longer time seems to be one of the main reasons for such pain, infact I myself was suffering through it but few exercises has helped me immensely in treating the same , you can try a few like cat and cow posture, leg raises, calf raises few streches etc. they are quite common and easy to do exercises which won't even take much of your time to perform ,I hope u can take out 10 min atleast for yourself and another important thing is Sunlight which we are completely deprived of during this time, make sure to get it for another10 min, m sure its going to help you ..All the best 👍
