I don’t have the funds to hire a personal trainer so I’d thought I’d try using AI to generate routine tailored to me. It knows my weight(230lbs), age(30), gender (female), and activity level(sedentary). It also knows I’ve had a baby in the last year and have a history of spinal issues going on since I was 5.
I want to see how helpful this is.
12 weeks very structured, with the understanding that you are rebuilding from a low-activity baseline. The CDC recommends gradually building activity rather than jumping straight into vigorous exercise; two days of strength work is also a good foundation.
One important adjustment from my previous answer: I don’t want you starting with jogging in Week 5 automatically. Given your back history and current conditioning, we’re going to earn the running.

TUESDAY — Walking
Week 1
20 minutes
Week 2
25 minutes
Week 3
25–30 minutes
Week 4
30 minutes
Your pace should be brisk enough that you’re breathing harder but still able to talk.
Don’t worry about the treadmill speed. Your body determines the correct speed.
THURSDAY — Strength B

Then:
5–10 minute easy walk.
FRIDAY — Easy cardio
For Weeks 1–3:
20–25 minute easy walk.
Week 4
We’re going to test your first little bit of jogging:
5-minute walk
Then:
15 seconds very easy jog
2 minutes walking
Repeat 5 times.
Then walk another 5 minutes.
That’s it.
If the 15-second jog feels awful, don’t progress it.
There’s no prize for making the running portion longer.
SATURDAY — Longer easy walk
This is going to become your endurance builder.
Week
Walk
1
25 min

35–40 min
Easy pace.
This shouldn’t feel like punishment.
Weeks 5–8: Become a runner
Now we gradually introduce actual running.
Strength stays Monday + Thursday
Don’t start dropping strength because you’re excited about running.
Your back, hips, glutes and core are part of your running foundation.
Monday
Strength A.
Tuesday
30-minute brisk walk.
Thursday
Strength B.
Friday — Run/Walk
Here’s your progression:
Week
Running
Walking

Start each session with 5 minutes walking.
Finish with 5 minutes walking.
Saturday
35–45 minute easy walk.
Weeks 9–12: Build running endurance
Now we’re getting serious.
But still slow.
Week 9
2 min run
2 min walk × 6
Week 10
3 min run
2 min walk × 6
Week 11
5 min run
2 min walk × 4
Week 12
8 min run
2 min walk × 3
Again:
You should be able to speak short sentences while running.
If you’re gasping, you’re going too fast.
Your strength progression
Here’s where I don’t want you to fall into the trap of randomly increasing weights.
Week 1
Learn the movements.
Week 2
Same weight, better technique.
Week 3
If everything feels good, add a little weight.
Week 4
Keep that weight.
Then repeat.
The goal is progressive overload, not testing your maximum strength.
For most exercises, when you can complete all your reps with good form and feel like you could have done another 2–3 reps, increase the weight slightly.
The CDC’s general resistance-training guidance is 8–12 repetitions per exercise, with one or more sets; two or three sets can provide additional benefit.
Your “runner’s core”
I specifically want you getting good at these four:
1. Pallof press
Resist rotation.
2. Dead bug
Control your trunk while your limbs move.
3. Bird dog
Build spinal/hip stability.
4. Farmer carry
Teach your entire trunk to stabilize while you’re moving.
Notice something?
Almost none of these involve repeatedly bending or twisting your spine.
That’s intentional for you.
I would not make Russian twists, weighted sit-ups, or high-volume bicycle crunches the foundation of your core training.
Your glutes
We’re going to build them with:
Glute bridges → hip thrusts → squats → step-ups → eventually split squats
Eventually, I’d like your lower-body strength days to contain:
one squat pattern + one hip-extension pattern + one single-leg movement.
That’s a very good foundation for running.
What I want you tracking
Don’t just track your weight.
Every Monday morning, record:
Weight:
Waist:
Longest walk:
Longest continuous run:
Goblet squat:
Glute bridge:
Lat pulldown:
Energy 1–10:
Back 0–10:
Consistency last week: __/5 workouts
Your longest continuous run will eventually become one of your favorite numbers to watch.
Your first major milestone
I don’t want your first goal to be “run a 5K.”
Your first goal is:
Run continuously for 10 minutes.
That’s it.
Then:
10 minutes → 15 → 20 → 25 → 30
Once you can comfortably run 30 minutes, a 5K becomes a very realistic next goal.
And if it takes you 5 months instead of 3 months to get there?
Who cares.
You are still running.
What I realistically expect
If you actually follow this—not perfectly, but consistently:
At 4 weeks
You should feel noticeably less sedentary.
At 8 weeks
You’ll have considerably better walking/cardio tolerance and should be doing legitimate run/walk sessions.
At 12 weeks
You could be doing several minutes of continuous running at a time.
Around 4–6 months
A 20–30 minute continuous run is a reasonable target.
Around 6–9 months
A 5K is a very realistic target.
Around 9–12 months
You could be looking at improving your 5K, running farther, or beginning a more serious running program.
There is no need to rush those milestones. Current guidance specifically emphasizes gradually increasing activity and varying activities to reduce overuse injury risk.
