Want firmer arms? Try regularly taking this 10 minute arms workout. This video focuses on the biceps and triceps, to get the fleshy bit on the back of your arms more toned. Grab some dumbbells - try 1kg if you haven't exercised your arms for a while, or 2 - 3kg if you regularly workout your arms.
Get rid of that loose fleshy bits of your arms by regularly doing this 10 minute arms workout. These exercises work on your triceps, the muscle at the back of your arm that is often neglected. Weights are optional, but I recommend using 1kg/2lb dumbbell weights if you have them.
In this video we will be working your shoulders, biceps and triceps. I've used 1kg weights, sounds small but they are mighty after a while of using them, option to decrease to 0.5kg or up to whichever weight suits your current strength. 30 seconds of work, 30 seconds of rest.
