Muster Seeds
Muster Seeds are open-source discipleship modules that combine physical training, discussion, and Scripture. Like a mustard seed, they are intentionally small—designed to help men gather, grow, and go wherever God has planted them. The ideal format is a 30-minute workout followed by a 30-minute Bible study, making them easy to use in churches, neighborhoods, and parks. Feel free to adapt, modify, and share. Feedback is welcome at info@musterseed.com.
1. Rally the Troops
In military units, a guidon flag serves as a visual reminder of identity, mission, and belonging. It literally means “guide of men.” Militaries would fly these banners to rally troops fighting on smoke-blanketed battlefields. Today, they guide marching troops. This workout reinforces that principle by repeatedly returning to the flag before moving back into the field.
Find a flagpole in a local park, bring a team flag, or create your own guidon.
Designate the flag as your rally point.
Establish multiple exercise stations around the flag (upper body, lower body, core, cardio, etc.). Designate them as battle stations.
Space stations at varying distances to encourage movement between locations. You could place it on the 50 yard line of a football field, and run to the corners of the end zones. Or you could put it in a park and set four stations in any direct.
Simply move to one of the battle stations, complete a circuit for 2-3 minutes, then sprint back to the guidon. Touch the flag. Add a couple burpees if you want to up the challenge, and then move to the next battle station.

Discussion Questions
Remember, the guidon is a key symbol of unit identity.
If someone asked you, “Who are you?” how would you answer? Where is your identity anchored when everything else is stripped away?
Can you identify a season of life when you drifted from your purpose or identity in Christ?
How are you intentionally helping your children, family, or younger believers stand firm against those same pressures?
Scripture
Exodus 17:15, Numbers 21:8, John 3:14. Read this study to build your plan.
2. Walk the Line
Jeremiah 12:5 asks a powerful question:
“If you have raced with men on foot and they have worn you out, how can you compete with horses?”
Before God prepares us for greater challenges, He often tests our faithfulness in smaller ones. This workout develops discipline, endurance, and unity by requiring the group to move forward together—one step at a time. This is illustrated through a FOD Walk — Foreign Object Debris. This is the same method used on Navy aircraft carriers to ensure small debris does not damage aircraft. One bolt can take down a fighter jet before it gets on mission. This workout shows the power of unity to sweep our lives clear of the same debris.
Establish a starting line and finish line. A basketball court works exceptionally well, but any training area will suffice.
Line up all participants shoulder-to-shoulder across the baseline.
Move across the court as a single unit while maintaining a straight line. No one advances ahead of the group.
Round 1: The Initial Sweep
Take one step forward.
Perform one push-up. Get up.
Take another step forward.
Perform one push-up.
Continue the pattern until the entire line reaches the opposite baseline.
The Launch
The moment the line reaches the far side, immediately transition into a full-speed run for a designated distance or lap.
Subsequent Rounds
Repeat the movement pattern using different exercises:
Walking Lunges
Air Squats
Bear Crawls
Mountain Climbers
Broad Jumps
Maintain the line throughout each round before launching into the sprint.
Discussion Questions
Identify your footmen. What small battles are currently draining your strength? Consider recurring distractions, compromises, temptations, and discouragements.
Where has God already proven faithful in your life? Where can you see victories already won?
Where have you seen another man in your group gain ground? Encouragement authorized.
Scripture
Consider this study on Jeremiah 12.
3. Throw Your Weight Around
Cast all your anxiety on Him because He cares for you. — 1 Peter 5:7
Peter wasn’t telling fishing stories. This isn’t a call to gently cast and reel in. Peter says we show throw, hurl, and aggressively toss our burdens to God to keep from allowing self-control to grow into pride.
What better way to illustrate that than to throw a heavy ball around for 30 minutes (or more).
Find one medicine ball. Heck, use your kid’s dodge ball if that’s all you have.
As a team, take turns throwing it down field. Add an exercise where it lands to scale up. Switch throwing techniques at each round — overhead, rotational, backward toss.

Discussion Questions
What specific weight or struggle do you desperately need to mentally and spiritually “cast off?”
What is one thing in your life right now that you are deeply grateful to God for? What is another? Keep that specific momentum going this week by starting a daily gratitude journal.
Scripture
Read 1 Peter 5:6-7 and Luke 19:35. Compare the physical act of throwing at Palm Sunday with the spiritual act of casting your cares to God. Use this as a guide:
Peter’s famous New Testament exhortation to cast our cares entirely upon God was inspired by Psalm 55. Also read this passage together with your group. You could even do two weeks in a row around this format.
