Lean Bulk Builder

I designed the Lean Bulk program to give you a blueprint for how I'd pack on lean muscle in just 4 weeks.

We'll train 6 days per week and we'll train hard.

Your split will be Legs, Chest, Back, Arms, Legs, and Delts before getting a rest day and then we'll get right back after it.

You'll be challenged by both the volume (the number of sets and reps) and the intensity (how heavy I'll ask you to lift) so this is not for the faint of heart.

But, if you've got 4 weeks and you're ready to commit to train like I do for 'em, you're going to get real results that you're proud of.

**Ready to pack on lean muscle mass?! **

Let's go!

FAQs
I just started training. Is this a good program for me?
Absolutely. I want you to focus on your technique over everything. The muscle will come fast so long as you stick to the plan + do the things you need to do outside of the gym to promote that growth (like fueling your body and getting your sleep).
How long is each training session?
We're getting a LOT done in just 4 weeks so I'm going to really push you. You should expect 40-60 minutes of training, 6 days per week while you're running this program.
What if I don't have access to a gym?
Check out the sample week of training before you get started. If you don't have most of the equipment, wait until you do have access to a gym to get started. Of course, when you're in a pinch, you can swap movements. But, I don't want you constantly swapping movements if you can help it.
