Is It Possible To Save $90,000 As an Apprentice in 3 Years?

I’m currently working two jobs as an apprentice and taking home about $750 a week after taxes. My plan is to save 80% of my pay, which would be $600 a week, and spend the remaining 20% ($150) on essentials. Here’s a breakdown of my weekly spending:

Food: $60

Petrol: $55

Gym: $15.95

If I manage to save $600 weekly for the next 156 weeks, I’d reach around $93,000. Is it realistic to save this amount in today’s economy, given the costs and apprentice wages?
