Frequently Asked Questions
How does the adjustable resistance work?
A simple mechanism lets you dial the tension up or down, so the bar matches your current strength and grows with you.
What muscles does it train?
Primarily chest, shoulders, arms, and upper back, with core engagement from the twisting motion.
Is it suitable for beginners?
Yes, start at the lowest resistance setting and increase gradually as your strength builds.
How much space do I need?
Very little. A few feet of clearance in front of you is enough for a full session.
How durable is the bar?
It is built from reinforced steel designed to hold tension reliably through thousands of reps.
