Does anyone have a good workout routine for Planet Fitness?

Can anyone suggest a good workout routine using the machines at Planet Fitness? I'm a woman, age 53, in pretty good health and physical condition. I'm interested in building stamina, losing a little weight and toning up. I want to spend about 30 to 40 minutes in the gym, probably three times a week. Thanks for all suggestions!Does anyone have a good workout routine for Planet Fitness?situps on slant board, hyperextensions, half squats with dumbells, lat pulldowns, decline bench press, leg curls then however much time you can spend on the elliptical
