Let’s take a closer at the Landmine Rainbow core stability exercise. For those of you who aren’t familiar with what the landmine is, it’s a barbell that slides into a sleeve so it becomes locked into a stable, pivoting point. I know many members at the BAC are 
unaware of this piece of equipment which is located on the new Synrgy 360 unit and also the squat racks. The rainbow is a great core stability exercise where the goal is to keep the spine from moving. Core stability is maintaining a stable and unmoving spine with some type of movement at the extremities, in this case the arms.
Muscles Worked:
- Quadratus Lumborm (lower back)
- Obliques
- Transverse Abdominis
- Rectus Abdominis (abs)
Steps to Execute Exercise Properly:
- With the end of the landmine up to the chest, assume a slight squat position
- Fully extend the arms in front of the body and draw the belly button in
- Lower the barbell to one side of the body while maintaining the spine in a vertical position
- Only allow the shoulders to move but NO rotation or tilting from the trunk
- Repeat for the desired amount of repetitions
Note:
Keep the top arm straight as the barbell moves to the side of the body. The body arm is allowed to bend at the elbow to help support the weight of the barbell.
