What beginners should prioritize

Ease of changing weights between exercises matters. Dial or pin systems usually beat spin-lock plates for circuit-style sessions.

Common beginner mistakes

Buying only very light weights that are outgrown in weeks. Skipping a mat. Learning Olympic lifts with selector dumbbells not designed for dropping.

Frequently asked questions

Do I need a bench immediately?

Not on day one. Floor presses and standing work go far. Add a bench when incline/flat pressing becomes central.
