One of the easiest ways to tone those arms fast is by incorporating some bicep curls into your routine. Simply raising and lowering a weight in a 180-degree range of motion, starting with your arm extended along your side, and bringing it up toward your shoulder, can yield serious definition in a hurry. Fortunately, this exercise doesn’t require a fancy gym membership or even special equipment; while it’s not hard to find a set of dumbbells for under $10, you can also use household products, like gallon jugs of water or soup cans to get the same result.
If you're ready to move on from classic Bulgarian split squats, Swan's amped-up variation gets your upper body in on the action for a true total-body exercise. "This combination move works your legs, butt, chest, back, arms, and core," she says. "And it not only hits all the major muscle groups—it also lets you work on balance." Give it a shot and you'll see why.
Not feeling up to heavy lifting? Try doing more reps at a lower weight instead and you’ll be kissing that arm fat goodbye in no time. Researchers at Canada’s McMaster University studied a group of 20-something men over a 12-week period, with half the study subjects lifting heavy weight and doing low reps, and another group lifting lighter weights for higher reps. The Journal of Applied Physiology study found that both groups increased their strength and muscle size by approximately the same amount, so if you’re relatively new to lifting or don’t feel up to hitting the heavy weights just yet, don’t worry; lighter lifts will still help you ditch the fat while gaining muscle tone.
