It has never been more crucial to get fit for the winter season. With the second wave of Covid-19 on the horizon and no signs of an early vaccine, you need to get yourself prepared. Colds and cases of flu abound as soon as the holiday season hits. This year, you cannot afford to come down with a bug or virus because you may need to self-isolate for other reasons. Getting fit for winter doesn’t just mean taking the usual supplements. You need to be more proactive in your plans.
