Upgrade your six-pack

Taking your existing six-pack to an even more impressive eight-pack isn’t the result of just any old generic workout. You have to treat your core like you would other muscle groups and devote a little time to each component. Jonathan Ross, the author of Abs Revealed, has designed these three routines to specifically target your obliques and upper and lower abs. By splitting your core workout across several days, you’ll ensure every section is worked comprehensively. And with each session lasting 15 minutes or less, you’ll have teased out those two extra abs in no time.
