I've been incorporating a lot of arm toning into my workouts lately since it's warm and I'm wearing a lot of tank tops and strappy dresses.
You can see my weights behind me in this photo. :-) Here's a tough weight lifting routine I did the other day. You might have to build up to it, but you'll definitely notice results if you stick to it!
Tank Top Arms Workout
Warm up with 10-15 burpees
Closed grip barbell on bench 3 sets of 12 reps
Bicep curl with barbell or dumbbells 3 sets of 12 reps
Overhead tricep extension with dumbbell or plate 2 sets of 12
Overhead tricep extension with barbell 2 sets of 12
Incline bicep curl 2 sets 12 reps/arm
10-20 tricep dips on bench
Bicep rows 2 sets of 12/arm
15-20 tricep push ups
Follow with some cardio or HIIT and you'll be "tanking" me. Get it? ;-)
Let me know if you have any requests for certain types of workouts or any fitness related questions! I'd be happy to put more workouts up.
