Just a general question about lifting while on gear. Perhaps the wrong forum. If so, mods please move.

When on gear, is it better to lift heavy with lower reps, or more reps at lower weights? I ask because the gym I go is a semi private gym. The owner is an IFBB pro and she trains us unless she's on vacation. Her husband fills in for her when she does sometimes. They have completely opposite training styles!

She does the low reps high weight, then when he comes in, we're doing like 3 sets of 30 reps at 20% of my max. Honestly, I hate his training style! lol I know there is merits to his style of weight lifting, but while I'm on gear I kinda feel like I should be lifting as heavy as I can every set to failure.
