No heavy equipment.
Your hands maintain your grip while your shoulders, arms, upper back and trunk help keep your body controlled.
That simplicity can be deceptive.
Holding your entire bodyweight from your hands for even 20 or 30 seconds can become surprisingly demanding.
The American Council on Exercise notes that dead hangs can be useful for improving grip strength, but also emphasizes that they require adequate shoulder mobility, stability and body awareness. They aren’t automatically appropriate for everyone.
