@chriver One, you're going to get rid of the whole 5x5 idea. It's not safe to train heavier with just dumbbells. Instead, you're going to do 3-4 sets of 8-12 for more reps.
You're going to find a dumbbell variation of every exercise, and use that.
At planet fitness they have a Smith Machine, but I don't think that's the best option. You can try it later, it's good for hypertrophy I've heard.
For example: instead of doing a Smith Machine Squat, do a DB Goblet Squat until you can progress to a farmer squat.
Instead of a barbell overhead press, start with dumbbells, this will help fix muscle imbalances, also, I just like it better regardless. Maybe doing a neutral grip on that exercise will help you see what you're doing better.
Dumbbell bench press, incline DB rows, etc.
Here's one I made for my friend:
WORKOUT A
•4x10 DB Lunge
•3x8-12 DB Overhead Press (Neutral Grip)
•4x10-15 DB RDL
WORKOUT B
•4x8-12 Goblet Squat
•4x8-12 DB Bench Press
•4x8-12 DB INCLINE ROW
Every week you workout as so: BAB
Now, you might be wondering, why so few exercises? Well, since you're brand new, you're going to need time to learn the exercises, and it's overwhelming to have to do a thousand at once. Start with these basic compounds, together, they will work every muscle in your body.
I'm making you do lunges because single leg training is desirable.
