STEP INTO SUMMER… THE 8 WEEK RESET

This isn’t a “get ready” plan.

This is the shift.

The one where you stop starting over…and actually follow through.

Step Into Summer is an 8-week, fully structured transformation designed to help you:

✔️ Lose fat
✔️ Build muscle
✔️ Lock in routines that actually stick

No extremes.
No guessing.
No starting over in 3 weeks.

Just a proven plan that works — if you do.

If you’ve been saying “I’ll start soon”…

This is your moment.

WHAT YOU GET WITH ‘STEP INTO SUMMER’

✔️ Lifetime access to Gym + Home programs
✔️ 5 workouts per week with a science-backed split
✔️ Step-by-step video demos + easy swaps
✔️ In-app tracking for lifts, progress photos & consistency
✔️ Private community + direct 1:1 support
✔️ Hands-on coaching & accountability for all 8 weeks

Everything is mapped out.
Your results come from execution, not confusion.

THIS IS FOR YOU IF…

• You’re done with the cycle of starting over
• You want structure without restriction
• You need real accountability (not just motivation)

Whether you’re getting back on track or leveling up…

This is where momentum starts.

🔥 GYM PROGRAM: STRUCTURED FOR RESULTS

No random workouts. No wasted time.

You’ll follow a proven 5-day split built for strength, muscle, and real body change:

Day 1: Glutes + Hamstrings
Day 2: Full Upper Body + Abs
Day 3: Quads
Day 4: Back + Shoulders + Abs
Day 5: Glutes + Abs

This is how you actually change your body:

Stronger lifts. Better shape. Visible progress, week by week.

🔥 HOME PROGRAM: SIMPLE, EFFECTIVE, NO EXCUSES

No gym? No problem.

30–45 minute dumbbell-only workouts designed to be efficient and effective. Perfect for:


• Busy schedules
• Travel
• At-home training

No matter your prior experience, everything is guided, explained, and adjustable to your level.

EVERYTHING IS DONE FOR YOU

✔️ Clear instructions
✔️ Full video demos
✔️ Modifications for equipment or injuries
✔️ Built-in tracking so you SEE your progress

All you have to do is show up.

ACCOUNTABILITY THAT ACTUALLY WORKS

This is where most people fall off.

Not here.

You’ll have:

💬 Weekly check-ins
🤝 Real accountability
📩 Direct access for support
🙌 Coaching & feedback throughout

You’re not guessing. You’re not alone. You’re locked in.

PRIZES

1st Place: $1,000
2nd + 3rd Place: $500

Winners are based on real transformations over the 6 weeks.

(Full before/after guidelines must be followed to qualify.)

You can go into summer wishing you started earlier…

Or you can be 8 weeks into feeling stronger, leaner, and more confident.

The choice is yours.

Let’s get to work.

If you have questions, reach out anytime at support@solinfitness.com, my team is happy to help.

I have been working out and programming my own programs for 2 years… I wanted to switch things up, do movements that I typically don’t because I honestly don’t like them, haha. I just started week 2 of built in 6 and I LOVE IT! I wake up at 4:00am for my workouts and it’s one of those programs that just make you want to get out of bed!

Solin has been a game changer! Especially with Erin! I’ve been following her for awhile and have a few of her workouts before Solin and it was just print outs that I would Follow. With Solin I’m able to have the workouts right at my fingertips and it keeps track of my previous weights. I’m able to do everything within the app and with my favorite fitness influencer! And cherry on top of this whole experience is the community! We get to interact with everyone doing the same workouts and even get nothing but positive feedback from Erin as well. I’ve been using it for 6+ months now and it’s been such a great influence in my gym experience.
