With temperatures dropping and thoughts of Christmas already looming, winter doesn’t seem too far away, but that’s no excuse to freeze our workouts says the popular PT. “Let’s get going,” she enthuses. “It’s in the Winter Arc that bodies are built! Don’t slow down, escalate.”

Try it for yourself:

Hanging Side Raises — 3 Sets x 6-10 Reps

Of course, blitzing those abs isn’t just about reps. “Ensure that you truly connect your core and control each movement from your abdomen,” advises Bergfoth. “No arched lower backs and no uncontrolled reps.”
