Gary has today off so we are hoping to get more house projects done. Mainly the second bathroom (future Baby M’s). I will share pictures tomorrow of the bathroom renovations! I can’t wait for it to be all done.

Michelle and I got up to do our workout first thing this beautiful morning. We forgot how much we miss working out first thing in the morning. We love how we have the rest of the day to enjoy 😉 We did a 12 minute plank core interval workout this morning from our club.  Michelle and I have a busy day ahead. We have a few videos to film, lots of editing and continue working on some new side projects.

And we are grateful for these sunny days to wear our favorite tanks. As we mention in the video we wished we were at the beach when we did this workout. Since we aren’t we had to visualize us being there instead. It worked.  The upper body is probably one of our favorite body parts to work. Not really sure why  but we love burning out the arms.

Time to get sexy strong arms!

Equipment needed: Nothing. You will be using just your bodyweight, so push yourself to get the most out of this workout! We have some fun new moves in this workout that we are loving and think you will too.

And this is a pregnancy safe workout. Time to get beautiful strong arms to hold your little ones 🙂

Here is the workout breakdown.

Don’t forget to PIN this workout to try this week and come back to let us know how you liked it!

16 minute interval workout to build lean strong tank top arms and core.

We suggest for different fitness levels:

B-fits (beginner peeps) – Follow video for recommendations. Set Gymboss Interval Timer to 12 rounds of 10 and 30. Just go down as far as you can in the monkey push-ups. And if tree pose push-up is too much just to side plank into a push-up on your knees.

A-fits (advanced peeps) – Go for speed. Push hard in the 30 secs.

FIT moms (pregnancy recommendations) – Do the modifications mentioned in the video. Set timer to 12 rounds of 10 and 30. Use a chair or wall for the monkey push-ups. For the side plank tree pose push-up do just side plank with no push-up, alternate sides each round. For the plank leg cross overs do curtsy squats instead.

16 minutes is all you need to feel the burn to fine tone those beautiful arms of yours!
