Here's a little tip that I thought would be interesting to share with you all to build up your upper body strength. It's really easy and takes no time at all but works a treat.
Begin by standing on a comfortable surface, where you have plenty of room at each side. With a 2kg potato bag in each hand, extend your arms straight out from your sides and hold them there as long as you can. Try to reach a full minute, and then relax.
Each day, you'll find that you can hold this position for just a bit longer.
After a couple of weeks, move up to 5kg potato bags.
Then try 10kg potato bags and then eventually try to get to where you can lift a 20kg potato bag in each hand and hold your arms straight for more than a full minute. (we are very proud, we are at this level)
After you feel confident at this level, put a potato in each of the bags.
