I'm 20, 150lbs, trying to bulk up.
My gym only has dumbbells up to 30kgs. I need a higher weight for my bench press but they don't have any. Are there any alternative compound exercises to target the same muscle groups? I would use a barbell but I don't have a spotter. Do I really need a spotter? I don't know if I'd be able to give it my all without feeling safe.
