The goal isn’t to lose weight, but it will happen with regular workouts. You’ll also improve your physical fitness and build muscle mass. Resistance training is also strength training. Robert’s analysis also clarified the role of intensity in muscle growth.
What are the Benefits of An Upper Lower Split Workout?
- Resting longer than 60 seconds between sets offers a small hypertrophy advantage over shorter rest periods, likely because you can maintain higher training volume when you’re less fatigued.
- For more, we’ve got a full article on how many reps to do.
- Exercise physiologist Rachelle A. Reed, PhD, ACSM-EP, recommends training for hypertrophy at least two days a week.
- But limited recovery time in this type of training can be detrimental.
- The workouts are like stepping on the gas.
- You want to make sure that you don’t push yourself too hard and end up getting hurt.
If you’re looking for an exercise program, you may have heard of strength training or hypertrophy training. They have some similar qualities, but their goals are different. One focuses on building strength and the other on building muscle mass. What Robert’s research reveals most powerfully is that these three variables do not operate in isolation—they work synergistically. A trainee achieving sets per week with moderate-to-heavy loads, distributed across 2-3 training sessions weekly, creates an environment optimized for muscle growth.

Every stroke becomes harder, slower, less efficient. Dr. Muscle guides you through your workout. It tweaks things in real time, just like a top trainer. You don’t have to think about it, it does everything for you. It’s a workout app, and it’s super smart. You tap a few times, and you get a custom workout.

Testosterone, one of the primary hormones driving muscle protein synthesis, requires a minimum of about 3 hours of sleep (including deep sleep stages) just to rise at all. But that’s a biological floor, not a target. Self-reported sleep durations in research on trained adults consistently average 7.5 to 8 hours per night, and that range aligns with what most recovery guidelines recommend. Over the next few weeks, we are going back to school for the foundational pillars of training, starting with hypertrophy. To make sure you are getting more than just gym folklore, we brought in Mike Young, PhD, kinesiology, director of performance & sports science at Athletic Lab in Morrisville, NC. He will be our go-to professor throughout this series, giving you the evidence-based answers you need to train smarter and see results.
Understanding Muscle Hypertrophy: The Science Behind Growth
If you want to help your clients get the most gains efficiently, you should consider upper/lower splits. This type of workout routine splits training into upper- and lower-body sessions. Two full-body sessions weekly, spaced 48 to 72 hours apart, strike the perfect balance—frequent enough to stimulate growth without making recovery the limiting factor. When sessions occur too closely, residual fatigue and muscle damage persist.
What Are Workout Splits?

Consider adding pauses at the bottom of the eccentric (lowering) phase, or adding a slower tempo to the eccentric portion of your lifts. Pauses remove momentum and force the target muscle to work harder out of the bottom, while a controlled eccentric increases muscle tension, which is a key driver of muscular hypertrophy. Fewer than 12 sets per week still produces growth, especially for beginners or for muscle groups that respond easily. But if a muscle is lagging or you’ve been training for a while, pushing toward the higher end of that range tends to produce better results.
In hypertrophy training, we focus on things like volume, intensity, and failure. We’re not just trying to move heavy weights from point A to point B. We’re trying to stimulate as much muscle growth as possible.
You don’t need supplements to build muscle, lose fat, and get healthy. But the right ones can help.
Whether you’re chasing muscle size, functional strength, or simply trying to break through a biceps plateau, these techniques deliver next-level results. In this breakdown inspired by a viral YouTube explanation, we’ll reveal the exact methods gymnasts use to build their biceps — and how you can apply them in your own training. Working out regularly is good for your mental health because it can help reduce stress. Strength training regularly can help lower your anxiety and reduce fatigue. It’s also linked to better self-esteem as you get stronger. Regular exercise reduces your risk of being overweight.
Sleep And Rest Days
Aim for controlled movement, perfect form, and progressive overload — even without weights. Isometric biceps engagement builds strength and muscle by creating sustained tension. This is particularly effective when the arm is slightly extended, placing the biceps in a stretched position. When performed with strict form — full range of motion, slow eccentric, controlled reps — chin-ups act as a compound “curl” with the added benefit of working the core and shoulders.
Technique: The Difference Between Training and Just Moving Weight
And as noted above, metabolic stress is one of the three causes of hypertrophy. Metabolic stress is often overlooked in building muscle, but it may be responsible for up to 25 percent of hypertrophy. Strength training also triggers a hormonal response that supports this process.
Days-to-Lean Meal Plan
Even if you’re doing all of the above, it’s important to remember that there are certain factors around building muscle that are out of your control. Your genes, for example, play a role in madmusclescommunity how much body fat you have—and therefore, how noticeable your muscles are from the outside. That said, “everyone can build muscles,” Miranda says—they might just not be as visible depending on your ratio of body fat to lean muscle mass. If you’re searching for strength training classes near you, Basecamp Fitness offers expert-led workouts designed to build lean muscle through hypertrophy training.
Having a plan can pay dividends towards staying consistent in the long term. Carbs help fuel workouts and replenish glycogen, giving you energy to push through harder sets and maintain intensity throughout training. Overall, the biggest influence on building muscle is consistency.
This cycle, repeated over time with proper recovery, is what leads to bigger arms. Lighter loads require more reps to reach that threshold, which makes sets longer and more uncomfortable, but the growth stimulus is comparable at the whole-muscle level. Heavier loads build more strength per set but accumulate fatigue faster. For most people, spending the majority of training in the 6 to 15 rep range and occasionally venturing outside it is a practical approach that balances growth, fatigue, and joint health.
High-intensity interval training is currently popular. But limited recovery time in this type of training can be detrimental. Achieving the right level of recovery time through upper/lower splits will help you maximize the results of your training. Those who trained twice per week experienced 6.8 percent growth in hypertrophy after several weeks, while those who trained only once per week saw gains of 3.7 percent.
