Build muscle and fitness without wrecking your body

Persist is the training plan that...

Shapes your body with muscle growing workouts
Gets you strong and fit as hell
Leaves burnout and injuries behind!

"From 183 lbs and not happy with body comp to 169 and shredded!"

"With proper nutrition and your workouts I have accomplished a look and a feel that I didn’t think I could get to! I’ll be 61 in December and never felt or looked better."

"New PR Alert!" (Power Clean - 200#)

"I’m up ~5 lbs of what must be muscle because pants fit tighter in the quads and shirts fit tighter in the chest. I’ve also noticed an increase in fitness."

"I'm excited about the progress I've made, and it feels like less effort than the past. I LOVE working out now."

Are you working hard enough to build muscle – without getting hurt?

To build lean muscle, you need:

Enough reps and sets of each area…
Working hard enough to see change…
But NOT so hard you get hurt…
Without wasting your time on moves that won’t work (or will bore you to tears).

How many days a week is Persist?

The PILLARS and MINIMALIST track are 4 days, and the PERFORM and PUMP tracks are all 5, plus optional recovery days. Persist includes instructions to optimize your muscle build if you need to train fewer times per week.

How long do workouts take?

What equipment do I need?

MINIMALIST uses dumbbells, a bench/box, and pull-up bar, or see the bodyweight-only workshop for alternatives. The other tracks use free weights such as barbells/plates, DBs, KBs, etc. and a rower, bike, or similar alternative. Substitution info is provided. PUMP LIFT also includes machine options found at conventional gyms.

What level of athlete is this for?

Athletes who get the most out of Persist are comfortable following a written workout along with demo videos, and ask questions if they’re not sure.

What if I am injured?

Injuries suck – so we try to keep them away through thoughtful movement selection. Many participants have healed nagging injuries by using the warmups, cooldowns, and recovery flows designed by our in-house Physical Therapist. Additional mobility videos are also included in Persist’s video library. And athlete support can answer any questions that might come up.

What if I miss a workout?

Persist updates training weekly, so there’s always a new way to build muscle. If you miss a workout, you can skip it to stay with the group, or use the calendar feature to go back to it any time.
