FitRene is starting up a new 4 week challenge at Pinkdumbbells.com that will focus on nutrition. Have you slipped back into some bad habits during this barbecue season? Well, you aren’t the only one!

Come join us at PDB for the You Are What You Eat challenge starting Monday, August 13 and renew your motivation! I’m giving away a new PinkDumbbells “Serious Pink” t-shirt that I will refashion into the winner’s choice of tank top, contrast shoulder (black or pink) tank top, or contrast 3/4 sleeve baseball top to the participant showing the most improvement based on stats and photos at the end of the 4 weeks.

The GrrlAthlete.com crew have come up with another efficient total body workout program called 6-Minute Circuits that is designed to be performed in under one hour, requires only dumbbells, and de-emphasizes the use of machines and running for cardio. Performed at the correct degree of intensity, the exercises in each circuit should keep your heart rate elevated throughout the entire workout.

The full e-book is $39.95 and includes 16 total circuits, but there is a free sample beginner’s workout from the book available for download now.

I haven’t tried it myself yet, but I will be giving it a go tonight. Any workout that doesn’t require me to hit the treadmill or sidewalks is worth a shot, eh?

I’ll let you know what I think tomorrow!
