Exercise isn’t about getting the perfect physique but about staying fit and healthy isn’t it? So, all u need to do to get started is doing a little at a time about 15-20 minutes each day and increasing it slowly so that your body can cope up. I personally feel that Emi Wong’s workout videos on YouTube are a good place to get started.
You can start by either downloading an app or watching YouTube videos. Depending on your goals, you can also make a week long exercise plan to repeat any time by researching the web as nowadays there are plenty of blogs about this topic with precise descriptions and pictures or videos to follow.
