FAQ section

Frequently asked questions


Do I need special equipment?

You’ll need basic gym equipment or alternatives like resistance bands and dumbbells for home workouts.

How soon will I see results?

First thing, results are NOT guaranteed because everyone's motivation, lifestyle, habits, and choices are different. Most women start noticing changes within the first few weeks, with dramatic transformations visible by Day 90.

What if I can’t complete all the workouts?

BellaBuild is flexible. Adjust your training frequency to fit your schedule while still seeing progress.

Will I have access to the workouts after 90 days?

YES! When you own BellaBuild or any other Erin Stern Fitness programs, you will always have access from your member dashboard.

WEEK 1


WEEK 1 of BellaBuild


  • As you begin this program, track the weights you’re using and work towards getting the prescribed number of reps.

  • It’s ok if you’re under or over by a few reps but be sure you’re close to failure (not reaching it) on each set. If you’re not comfortable doing that with a specific exercise, simply add more reps.

  • Make sure to warm up by walking, biking, jogging in place, side stepping, or jumping rope for a few minutes before warm-up exercises.

  • Allow up to 3 minutes rest between compound exercises, and 45 seconds to one minute rest between isolation/easier lifts.

  • Keep an eye on recovery between sets.

  • For leaning down, you can shorten recovery between sets. As long as you feel recovered, you can start the next set.

  • For more details, see the Getting Started page and video.

WEEK 7


WEEK 7 of BellaBUILD



  • This week, we’ll introduce some new techniques such as pre-exhaustion and drop sets.

  • Leg extensions before performing compound movements is an example of this, as the leg curls will pre-exhaust the quads and help other muscles work harder.

  • For the drop set, you’ll do as many reps as you can, go to a lighter weight and repeat until failure. Then, you’ll decrease the weight once more before going to failure again. 

  • Make sure to warm up by walking, biking, jogging in place, side stepping, or jumping rope for a few minutes before warm-up exercises.

  • Allow up to 3 minutes rest between compound exercises, and 45 seconds to one minute rest between isolation/easier lifts.

  • Keep an eye on recovery between sets. For leaning down, you can shorten recovery between sets.

  • As long as you feel recovered, you can start the next set.
