Carrie Underwood and Mike Fisher are sweaty sweethearts! Isaiah Michael Fisher's parents got in a workout together Thursday morning, but it looks like mom might have been taking this post-baby fitness sesh a little more seriously than dad!
The "Little Toy Guns" singer Instagrammed a makeup-free selfie with her NHL star hubby that showed the twosome on what appeared to be in-home stationary bikes. Carrie held up a rocker symbol while Mike was either a) resting between sets, or possibly b) really into a set?you can be the judge of that one.
