About 10 minutes of my MuTu system stretches and core exercises that include squats, some bands, ball between the knee squeezes and other such exercises.
First I did a 20 minute walk. I know, it sounds lame but I really enjoy just being able to get out (except for all those stupid mini flies...the downside of living near a lake I guess). As light as walking is I can see how it can help get contractions going, I tend to feel extra pressure down low in my belly almost immediately!
Then after I got home I did Tiffany Rothe's ten minute "Pretty Positive Pregnancy" toning video here;
HR: after the video it was 130-140 and I assume near the same during my walk
Sweat'o'Metre: I got the body temp up during the walk and video but not much sweat
Burn'o'Metre: biceps and shoulders man, she kills me in this video I've gone from cans of beans to cans of soup :P
