1. Jab, cross punches

It’s the ol’ one-two! You can make this one a bit trickier with some hand weights if you’re up for the challenge. Don’t have any weights? Yeah, you do! Just use weighted balls, water bottles or soup cans.

» Stand side on with your guard up (elbows close to your body and fists protecting your chin).

» Perform a quick jab with your front arm and follow up with a cross punch with your back arm. Keep em coming!

» Remember to roll your shoulders through the movement too to get your abs involved.
