Late 50's needing support to start strength training

[userOT6QGRLLYLP]

Hello! My name is Richard and I'm looking to start strength training and could use some support. I've had gym memberships in the past but never used them. In 2017, I lost 70 pounds. I've managed to keep it off but I've gained 20 pounds in the last year. Would be grateful for support and encouragement and ideas. I go to the gym and have no idea where to start. I need a workout that is easy and fun so I stay engaged and don't get bored
