*Resting a few extra beats longer before your next set - Totally ok...good sometimes I just need a minute especially during obliques crunches...ouch!

*Skipping cooldown - WH says it's fine to let your heart rate come down just from normal activity...I really never saw the point in neck rolls anyway.

*Shaving off the last couple reps - It's a no-no...Push through and stress your muscles - it makes those body changes you're looking for.

Also in the issue - some popular moves which will get your arms ready for sleeveless by summer!  For more tips follow WH on twitter.
