Hello, I am trying to work out more and become less lazy. Here is my current workout plan:

1) Squats, 1 set of 12 reps

2) Dumbbell bench press, 30 lbs. 8 sets of 8 reps

3) Bent Rows, 4 sets of 10 reps 25 lbs.

4) push ups, 1 set of 10 reps

5) Curls, 2 sets of 13 25 lbs.

6) Glute Bridge, 10 reps

I am 14 years old, 150 lbs., 6 ft. 2 in.
Is this a good workout? Any suggestions? Also, how often should i work out because clearly by how much i lift, im not very strong. Thanks!
