What should I feel during Machine lateral raise?

Side delt shortens across the entire arc — machine keeps constant tension.

What are common mistakes with Machine lateral raise?

Seat too low forcing trap recruitment; Jerking through sticking point

How do I progress Machine lateral raise?

Add load after consistent full-range reps with no trap flare.

What can I do instead of Machine lateral raise?

DB lateral raise (strict), Cable lateral raise, Band lateral raise

Machine lateral raise
