Hey Marc, no matter what I do, I can not get a pump in my left arm. I use dumbbells for things like curls and bench, and focus on my form to make sure I'm not favoring one side. Both arms reach failure at the same amount of reps so I know I've evened out the strength imbalance I had from a previous hand injury. However, while I feel an AMAZING pump in the right arm, the left barely feels pumped at all by the time I'm done with my post workout shake. What is the issue, and what can I do to feel that amazing swoleness on bother sides?

Marc what are your recommendations for maintaining joint health and skeletal muscles? I'm about 35 and have been an athlete / training for going on 20 years, wear and tear are becoming a concern. Thanks!

what are the benefits of usin natural test boosters during a cut??

Hi Marc,

I was thinking of starting intermittent fasting in an 11am-7pm window since it fits my college schedule. However, I don't want to hurt my muscle gains since I plan on lifting 6 days a week. Will IF hurt my gains? Thanks

I am 115 lb female And looking to try adding in the squat a day program. I currently do squats with working sets of 150 lbs on leg days. What would a good weight sequence be to get the most benefit but not over work my legs. Thanks, Kila (yes, rhymes with tequila 😋)

Hey Marc,

I saw this article by Michael Matthews, author of Bigger Leaner Stronger, basically says that BCAA does not live to the hype except if you're using it during fasted cardio/training. He also said:

"All we currently have is an unpublished study paid for by Scivation–the creator of the popular Xtend BCAA supplement–and headed up by Jim Stoppani, that…cough..demonstrated?…some remarkable results" https://www.muscleforlife.com/bcaa-supplement/

“The skeptic in me is tempted to chalk up some of the results to not just funding source (Scivation), but also the longstanding friendship between Jim Stoppani and the Scivation staff. The fact is, there’s no way to quantify the degree of commercial bias inherent in this trial – or any other for that matter.” https://www.muscleforlife.com/bcaa-supplement/

1. What are your thoughts on his claims?
2. What are your thoughts on the 10:1:1 type of BCAA's and how is it different from the 2:1:1?

Acetyl l-carnitine is raved about for fat loss and i ordered if it was necessary to stack drop factor with it.
