FREQUENTLY ASKED QUESTIONS

Old School Iron is best described as a Power Building Program. Focus shifts from strength to hypertrophy. With that said, the focus is 100% on building mass. There is no conditioning, but rather a laser focus on building muscle.

Yes! Even though Old School Iron is an advanced program, you can complete the first month at a slower pace and repeat it until you’re ready for the more intense months that follow.

You will be training 5 to 6 days a week. With 4 unique months of training, this will vary depending on the mode you’re training in and specific goals of the phase, but this is a high volume, intense program.

If you have a gym membership, you’ll have everything you need to do the program. If you train at home, a barbell, pullup bar, bench, dumbbells, and resistance band are recommended.

Yes! We know there are more than a few women who are up for the challenge. Unlike some of our programs that have multiple focuses, Old School Iron is designed specifically to build muscle. If that’s something you’re looking for and are OK doing the old school classic lifts, then by all means YES!!

Absolutely. You will need some experience in the weight room to have success with OLD SCHOOL IRON as it is not a total beginner program, but if you want to add muscle then you’ve come to the right place!

Yes. I’ve got you covered with a day by day nutrition plan.
