Split the pot

10% is easier when you break it up, so each round has its own goal - and its own pot to split.

How do you verify the weight loss?

For all official weigh-ins, you'll be prompted to submit your official starting weight. Our standard weigh-in process involves you submitting 2 photos: one of you standing on a scale in lightweight clothing (no shoes, hats, belts, watches, coats, or outerwear), and another of the scale’s readout with your weigh-in word written on a piece of paper.

What you'll need

  • A scale (preferably digital)
  • A digital camera or smartphone
  • A full-length mirror or someone to take your photo

  • Does anyone struggle with this?

    Our desire to do things "perfectly" can have such an opposite effect. When we don't live up to those expectations, it can really send us into a tailspin can't it?

    This is your reminder that it's not all or nothing. Real progress will only come when you let go of "perfect" and start thinking of a trajectory that is slowly going in the direction of your goals. You got this!!

    Who can relate to this? Has anyone been successful in changing their mindset?

So true! I try to remind myself that 5 out of 7 days are still way better than nothing but it is still discouraging. Still working on the mindset.

This has been one of my biggest roadblocks to eating healthy and losing weight. Getting better at it though :)

  • Research shows that short bursts of activity can improve overall health and weight loss and ditching the “all or nothing” mentality may help individuals be more consistent with their activity.

    Breaking exercise into small chunks on your overscheduled days can also keep your confidence up, since skipping it altogether can make you feel tired, guilty, or depressed.

    To get us all thinking, here are 5 ways to get a burst of energy in your day.

    1. Jog in place, squat, plank, or wall sit during commercials (or between episodes while streaming).

    2. Dance like nobody is watching! Have a 5-10 minute dance party and see if it doesn’t also elevate your mood!

    3. Spend 5-10 minutes walking or climbing stairs for every hour you spend sitting at your desk.

    4. Do standing pushups (against the wall or counter) while waiting for dinner to cook.

    5. Do a quick sweat-sesh before each shower. Try a few kettlebell swings, burpees, jumping jacks, lunges, etc.

    Is there something you do each day that you can turn into 5-10 extra active minutes? Share some ideas you have!

Love this thank you.
I used to do squats in commercial breaks on tv, but I rarely get tv time anymore

Rowing machine or bouncing on a yoga ball while swinging my arms like I'm running. Great with hand weights too.
Great activity for foot injuries too if you can manage with your leg elevated.

  • It's rainy so I'm doing mall laps. I think the Conquerer Grand Canyon challenge is motivating me to get mini walks done during the week to stay ahead of their estimated pace for me. I want to do 20km a week which is 2 runs. Plus the walks maybe 26-29km? I dont promise anything because I'll quit if the demand is too high. Just gotta do my best!

  • I found another rhododendron! It's mostly hidden on the other side by azaleas. But I walked along the back side of it and caught this view. It is loaded! Gorgeous!

I think today's workout was the hardest workout I've done this year. The entire thing was a fight not to quit ( mentally, that is. My body quit on me quite a few times lol ). So thankful it was only 45 minutes long. I like the workouts that make you dig deep because they test your mental strength, but boy do they suck while you're doing them!

  • I am loving eating clean after indulging in sushi and some other stuff over the weekend! We have garden fresh asparagus and it is just amazing!

Looking up nutritional information after eating like...



Run. Uphill. Clenching abs. Fanning arms like a broken windmill.

Anyone have been diagnosed later in life (over 40) with gluten intolerance (celiac) or other digestive problems and have good recipes that help make the transition easier?

A great place to start is with googling "Whole30 recipes" everything will be gluten free and you don't have to triple check.

Lindsay B.

I have Celiac! So many good foods available to substitute now. Almond flour is a great sub in foods like meatloaf, meatballs, etc. Gluten Free pasta is available, I like rice pasta best. Danielle Walker's website Against All Grain is a great starting point and her cookbooks are delicious too.
