3 Single-Leg Movements You Shouldn’t Skip

 by on April 21, 2025

Single-leg training, particularly with free weights, can hold an incredibly valuable place in a well-rounded training program, not only because of the added muscle development that training one leg at a time can bring, but because they can help preserve joint health and maintain flexibility and mobility at the same time.

Setting Up a Mini-Cut

 by on March 26, 2025

Mini-cuts are a very popular tool for dieting – searching Instagram for the hashtag #minicut gave me several hundred thousand results. But there are, in general, two ways that most people are using it, and one of them is much more effective than the other.

How to Stick to a Diet when Traveling for Work

 by on March 19, 2025

I recently spent a week out of town staying at an Airbnb and had very limited access to cooking, with a kitchen that just had an electric stovetop, a microwave and a toaster. Take a look at how I stayed on track the whole week by making two stops at grocery stores before going to the rental, as well as what I brought with me in my suitcase.

The PERFECT Back Workout

 by on March 17, 2025

This all-around back workout is one of two that I’ve been using that cover a bit of everything you need – movements to feel your lats and prime them, heavy rowing, upper back work, vertical pulling and lower back work for recovery. Try it, you won’t be disappointed!

A Guide to Intensity Techniques

 by on February 24, 2025

While the vast majority of your training should be comprised of standard-issue straight sets (a single set performed at or near failure, followed by a rest period), there can be value in the intelligent use of different intensity techniques that go beyond what a straight set will allow.

Magnesium is easily one of the more underrated supplements in the fitness industry – it contributes to more than 300 chemical reactions in the body, including energy production, maintaining insulin sensitivity, protein synthesis, and much, much more.

Using Supersets for Opposing Muscle Groups

 by on January 30, 2025

In bodybuilding, intensity techniques such as drop sets, rest-pause sets, static holds, and partial reps are fairly commonplace as a regular part of training. Another technique that I think personally gets overlooked is the superset and its variations.

Thickness-Influenced Glutes & Back Workout

 by on November 25, 2024

My primary offseason focus for the last few years has been to bring up my physique from the back – while I know I need to add more tissue overall to get closer to the top of my weight cap for classic physique, as any competitor knows, most shows are still won from the back.

Single-Leg Lactic Acid Torture

 by on October 28, 2024

This is a workout that I started using regularly when I was dealing with a lot of lower back issues – it doesn’t look like much on paper, but it will put your tolerance for lactic acid to the test for sure. It’s also a fairly short workout, coming in at about 45-50 minutes from start to finish.
