You know those girls on Instagram/the beach you admire for their impossibly toned tummies? They're all tanned skin and taut muscles, with a hint of sexy definition running down their abdomens — and they're a leading source of bikini-body inspiration as the weather starts to warm up.
We're over halfway through August; less than two weeks until it hits Spring and we start busting our bikinis out. With the help of qualified personal trainer Matt Flynn, we've devised a 31-day workout for you to test yourself with. Combined with a balanced diet and your usual cardio, this plan will test your limits and give you tummy muscles you never even dreamed of — so come Spring-time, you'll be ready to go. Missed the start date on August 1? This challenge is one you can do anywhere, any time. No excuses!
