Hey, was lifting for awhile with the main goals of strength and little bit of mass, but massive life changed have caused me to take over a year off, now I have at most, 30 minutes a day. I was wondering if I could get some opinions on if you guys think im just waisting my time or if I should expect any results from this.

An example of a weekly routine

Monday-
Lunges 3x10
Various core

Tuesday-
Dumbbell curls 3x10
Barbell curls 5x5
Dumbbell row 5x5

Wednesday-
Military press 5x5
Front/lateral raise 3x10
Various core

Thursday-
Bench dips 3x10
Tricep extensions 5x5

Friday-
Bench press 5x5
Dumbbell press 5x5
Various core

I work out at home and currently its nearly impossible to do squats but i really wish I could, and that's not an exact layout just general reference, I change it up a lot. But just wondering if that's too little, and any suggestions or advice would be much appreciated, thanks.
