Stand with legs shoulder width apart, knees slightly bent. Here are some exercises that do not involve weights ad which will tone your arms in a fun way. Bring your arms to shoulder level. Extend them outward and forward. Do five sets of ten repetitions. Do the same out on each side. Do the same over your head. Never lock your elbows.
Now involve your oblique muscles. Twist your waist so that you do the same with your arms diagonally. Do five sets of ten repetitions for each arm being forward diagonally first. Now leap across the floor using opposite arms and legs. This all can be a warm up routine.
