Ben Foden's six-pack workout

The frog sit-up

Try this spin on the classic sit up. This position, with your thighs out to the side, takes your hip flexors out of the equation. What does that mean for you? Your abdominals will have to do all the work. Ouch.
Ben's top tip "Instead of putting your hands behind your head, slide them up the legs with every rep." Maintain slow, steady movements on the way up and down – don't flop.
