Since 2009
THE PRAYFIT DEVOTION
Oxygen Debt
As athletes, you know the feeling; hands on your knees, trying to catch your breath after a grueling set of wind sprints. You try and stand tall, putting your hands on your head, desperately gasping for air. Before you know it, coach blows the whistle for the team to get back on the line to do it all over again.
In exercise physiology there are all sorts of wonderful phenomena going on inside your body immediately following an intense bout of exercise. One of the more traditional terms tossed around, and one that was hammered into my head during graduate school, was the term "oxygen debt." And for the sake of the conversation, you can think of oxygen debt as recovery time, or the amount of oxygen required during recovery to get your body back to a steady, normal state. The thing of it is, while it's called oxygen debt, it's not something you can actually pay back.
You know, Rev. Scotty Smith says, "Breathe in God's grace like you breath in air. It's just as vital, actually, more so." Reading that makes me think back to those old days of training. If you're a swimmer, maybe the gasp just above the water is a better picture. Either way, air is vital for our survival. But even more so is the grace that God offers us through Jesus. And the sin debt He paid in full on the cross of Calvary is a debt we can't repay. Good works -- when performed to try and keep us in good standing -- will only leave us gasping; think of a fish out of water. That's us without grace.
So with the wonderful Lent season fast approaching, keep that in mind. Grace allows us to breathe easy while we work. Because no matter your success or failure at whatever commitment the beautiful Holy season inspires in you, God can't love you any more than He does right now. So don't try and repay Him. Simply accept His grace, take a deep breath and sigh.

For Discussion: I like what Louie Giglio says: "For Lent, I'm giving up." For some of you, Lent represents an amazing time of renewal and commitment. Perhaps you're making commitments to read your Bible daily, or give up sweets, or television. Some of you will use this time to realign yourself with healthier foods and choices to exercise. Others will take what Louie said and simply give up trying to be perfect. Well, whoever you are and whatever your needs, we're here with you. God bless you and all of us as we're mindful of the coming season where God conquered death and the grave so we wouldn't have to.
CARDIO CORNER: If you participate in athletics, or any kind of intense activity, you're well aware of the feeling right after a bout of exercise. And EPOC -- excess post-exercise oxygen consumption (often used interchangeably with the term oxygen debt) -- is the number of calories expended (above resting values) after an exercise bout.
EPOC represents the oxygen consumption the body uses to return to its pre-exercise state. The physiological mechanisms responsible for increased metabolism following exercise include oxygen replenishment; phosphagen (ATP-PC) resynthesis; lactate removal; and increased ventilation, blood circulation and body temperature. The body generally takes anywhere from 15 minutes to 48 hours to fully recover to a resting state. Studies have found that the magnitude and duration of EPOC depend on the intensity and duration of exercise. Other influencing factors include training status and gender.

We Are The Crowd
"Jesus stopped and said, 'Call him.' So they called to the blind man, 'Cheer up! On your feet! He's calling you!' Throwing his cloak aside, he leaped to his feet and came to Jesus."--Mark 10:49-50
Read: Mark 10
No need to adjust your computer screen, that’s indeed the same verse as yesterday's entry. But I just had to go back to it. Ever since we posted last night, I haven’t been able to get a particular thought out of my head: The crowd knew something. Read the verse again.
Typically, we focus on either the blind man, Bartimaeus or, of course, Jesus. But the crowd's response has bugged me for nearly 24 hours. The crowd is…us. Why? Because they knew something. They knew what Jesus had the power to do in the blind man's life. Otherwise, they wouldn't have reacted as if the beggar had just won the lottery!
Read it again. Of all the thousand voices that were clamoring for Jesus to hear, that of a blind beggar behind all the others sitting on the side of the road found the ear of Jesus, and the crowd knew what that meant. Can't you just see them pause, their wide eyes, open mouths, and then their whiplash reactions as they run to the one who's number had just been called?
You and I stand among those who need to heed the call. Read the verse again (last time, I promise). Isn't Jesus calling everyone? Didn't He die for all the world? And if we've been saved and healed…aren't we the crowd who knows?

Question: Who in your life needs to know what you know?
GYM TIP: There's more than one way to use a treadmill. A recent study found that those who pedaled backward on treadmills and elliptical machines gained greater quadriceps and hamstring strength and had greater aerobic capacity than those who went forward. Click here for more.
Peña to be Honored by UT Tyler Alumni Association: Next Friday (March 22), the University of Texas at Tyler Alumni Association will recognize five graduates at its Alumni Gala. Among those being honored will be PrayFit founder Jimmy Peña, who earned a master of science in clinical exercise physiology from UT Tyler in 1998. "It’s easy to think of Heaven on days like this," he said. "We’ve accepted an invitation we don’t deserve, to celebrate a reward we didn’t earn." Click here to read more.
How Deep Is It?
"For to us God revealed them through the Spirit; for the spirit searches all things; even the depths of God." --1 Corinthians 2:10
Read: 1 Corinthians 2
During Memorial Day weekend, I overheard some kids as they were running toward the pool. They had it all. Towels, floaties, goggles. I think I even saw Scuba Steve hanging out of a bag somewhere. But it wasn't what they were taking to the pool that caught my attention, it was what they kept asking: "How deep is it?!" One kid asked, then another and another. Their dad, carrying all the tools for the fun, simply said, "Go find out!"
I remember asking that very question at each new pool we visited as kids. Going over to a friends house to swim, "How deep is it?" Maybe you did the same. But one thing is for certain, we asked it on purpose. Why? Well, it wasn't because we planned to stay in the shallow end. It was because we were going to A) dive in and B) try to touch the bottom of the pool.
When it comes to our lives and our health, let's be kids again. Splash around. God has given us this one life, so let's go find out. I like to think He enjoys watching us run to the day's water with one question ringing in His ears.

FUN FACT: AQUA CARDIO
While you're scrambling around this week figuring out what to do to start reclaiming your health, you may want to consider hitting the deep end and splashing around, literally. (Okay, maybe with a bit more purpose.)
Did you know that swimming can burn 430 calories in a single, 30-minute session? That's right, "chasing the black line" in your local lap pool could help you get in shape quick, and with less stress on your joints. Swimming with high effort using the standard freestyle stroke tops some of these other activities in total calories burned over 30 minutes:
High-impact group aerobics - 301 calories Walking on 10% incline, 3 mph - 319 calories Bicycling, 12-14 mph - 344 calories Running, 5 mph - 372 calories --Estimates based on a 180-pound individual.

POWER AND STRENGTH
January 26, 2011 "We can be tired, weary and emotionally distraught, but after spending time alone with God, we find that He injects into our bodies energy, power and strength." --Dr. Charles Stanley
In "PrayFit: Your Guide to a Healthy Body and a Stronger Faith in 28 Days," we advocate spending a few minutes each day working on faith and fitness. No matter what time of day you choose to do this, life can make it difficult to muster the motivation to work on either. Long work days, kids running you ragged, all-night study sessions, brutal commutes, bad sleep -- even amidst the status of a life lived well, cracking open your bible and then working up a sweat may seem such an extraneous and wholly dispensable chore. But by making that time and keeping that morning meeting with the Lord, you will be amazed at what you are able to accomplish, not just for the workout that follows, but for the day ahead. Energy, power and strength -- byproducts of a commitment to faith and fitness. Dr. Stanley was on to something.
WE'RE PACKED AND READY
During a recent interview about the book, we were asked if we traveled to churches and groups to discuss faith and fitness. And our answer was a resounding "Yes." And so we'd like to share the same with you. Please talk to your Pastor or church leaders. Give them a book and reach out to us to discuss the Prayfit Team visiting your community. We're packed and ready to help you and yours take back your health for the Lord. Remember, something so fearfully made deserves more attention and upkeep than what we as a nation of believers are giving. And we want to help.
