Now there's NO excuse not to work those biceps.  Okay, don't run a mile at the thought of combining sexy time with your work out. With this position, we promise you won't even notice you are exercising. It's called "The Wheelbarrow" and is excellent for achieving deeper penetration if your guy is on the smaller side, as well as working your arms and shoulders. How it's done For this position, he needs to be standing behind you. Get on all fours just like you would for doggie style, and let him lift you up by the hips. Wrap your legs around his waist, linking your feet at his lower back to get a good grip. From here, you can let him thrust to his heart's delight, or for an added workout boost - ask him to stay still and let you control the pace. Lazy girl cheat For a twist on the position, get your man to kneel near the side of the bed, put your arms on the floor and wrap your legs around his waist. Your knees on the bed provide extra leverage here, taking some of the pressure off the arms. This is also a handy cheat if your fella is well endowed as you have more control over how deeply he penetrates. This position works the biceps, triceps and shoulder muscles - win win! So there you go - toning while you're boning.
