Working out only takes 20 minutes out of a day

[n9wiff]

Lifting weights for at least 40 minutes. I need 4 minutes to recover between the series, is that too much?

I'm not sure, I'm small and weak so you shouldn't take advice from me 


I'm not experienced, but I typically need about 2 to 3 mins

And do like only 2 sets per muscle group
