1:16:03 Which muscle groups are really targeted by the back squat? Greg discusses his new article, which is available here: https://www.strongerbyscience.com/squats-adductors/

1:32:39 To play us out: A gentle reminder that GREG IS NOT A HOST.

1:34:30 Interview with Dr. Eric Helms

1:34:58 Eric Helms’ background

1:39:37 Helms is currently prepping for a bodybuilding competition. Compared to previous competition preps, what is he doing differently this time around?

1:40:51 Doing contest prep without strictly tracking macros

1:48:31 How low do Helms’ calories get during contest prep?

1:54:05 How long is Helms’ current prep going to be?

2:00:12 When you get late into a weight loss phase, do you cut down training volume or intensity?

2:06:37 Are you doing anything to proactively address reductions in non-exercise activity thermogenesis (NEAT) during contest prep?

2:07:33 Helms and Trexler bash the regular use of HIIT during contest prep

2:08:02 Does Helms have any strategies or approaches that he likes to use, despite the fact that they aren’t necessarily backed by scientific evidence?

2:10:02 What are a lot of bodybuilders getting wrong these days? (Discussion: Ideal training frequency for bodybuilding)

2:13:54 Training studies are often quite short, and in relatively untrained people. Do the results from these short-term studies translate to long-term differences over a training career?

2:19:31 Is bodybuilding unhealthy? Should it be encouraged?

2:28:11 Helms plugs his “podcast” with Omar Isuf
(Note: after a thorough review, it does not meet the Stronger By Science criteria for formal identification as a “fitness podcast,” and therefore is not the first fitness podcast ever)

2:30:50 How can people get in touch with Helms?

Q&A: CBD, Junk Volume, Eccentric Training, and Building a Following in Fitness
01:25:00

Remember: If you want your questions answered on a future episode, submit them using one of the following links: Facebook, Instagram, and Twitter.

TIME STAMPS
3:31 “What is your opinion on CBD?”

10:07 “Does volume or intensity drive strength gains?”

20:10 “Is ‘junk volume’ a real thing?”

23:53 “If we say that metabolite accumulation may play a causative role in hypertrophy, shouldn’t that mean that supplements designed to enhance the pump actually increase hypertrophy?”

39:14 “I’ve read that having a lower body fat percentage is more conducive to building muscle/strength. Is there truth to this, or is the change in body function/hormones negligible between high and low body fat percentage?”

48:19 “How possible is it that eccentric overload causes preferential hypertrophy of titin, meaning that people who only perform conventional training get a percentage of the available gains? What study designs/tools (blood markers, biopsies) would you use to test? If true, what kind of difference do you feel it would amount to?”

57:16 “In regards to re-feeds and/or diet breaks, from what I understand at least 2 consecutive days of re-feeding is needed to have any impact on the metabolic adaptations of a prolonged calorie deficit (3 days is probably better). That being said, how much of an effect does it really have, and is the cost to benefit ratio really worth it?

1:06:18 “How did you (Greg) build a following in the fitness industry?”

Q&A: Dropping Weight, Building Strength to Promote Hypertrophy, and Training Around Pain
01:17:14

Remember: If you want your questions answered on a future episode, submit them using one of the following links: Facebook, Instagram, or Twitter.

TIME STAMPS
0:57 “Is there any carry over or need to develop strength in the 1-5 rep range in order for that strength to be carried over into the 8-12 rep range for hypertrophy promotion?”

Meta-analysis of high load vs. low-load training; similar hypertrophy in spite of different strength gains. Also worth noting that the theory behind reverse linear periodization (starting with low volume/high intensity and progressing to high volume/lower intensity) is that early strength gains will help lead to more hypertrophy, but that’s never panned out in the research (one example here).

14:33 “When in a caloric deficit, should you reduce training volume, or training intensity?”

Localized depletion of stored glycogen.

27:11 “How should you train for explosive activities, such as parkour?”

Individualized programming for people with force vs. velocity deficits.

54:30 “When you have pain during a certain exercise, how do you decide whether it’s worth rehabbing that movement vs. picking a different exercise?”

58:29 “What things have contributed most to your success in powerlifting/bodybuilding?”
