"Are there any negative effects of a high rep range workout?" Hi my friend, When it comes to high rep range workouts, there are a few things to keep in mind depending on our fitness goals. High rep range is defined as more than 15 reps in a set, and it's traditionally known to help us develop our strength and endurance. As we progress with our workouts and start hitting those higher rep ranges, we're essentially pushing our muscles to their limits, causing them to adapt and grow. Here are the rep ranges for different fitness goals: 1–6 reps for gaining strength 6–12 reps for hypertrophy or building muscle size. 12 reps and above for improving muscle endurance. Our muscles are made up of two types of fibers: slow-twitch and fast-twitch. “Twitch” refers to the contraction, or how quickly and often the muscle moves. Slow-twitch muscle fibers are all about endurance or long-lasting energy. In comparison, fast-twitch muscle fibers give you sudden bursts of energy but get t...

Maryam asked "What are the phases of a muscle twitch?" Hey Maryam! Picture our muscles as a squad of dancers, each led by an  alpha motor neuron . These neurons branch out, connecting to a bunch of muscle fibers, forming a motor unit. When these guys get the signal, they contract, creating a muscle twitch. A muscle twitch has  three main phases : Latent period  - the calm before the storm, a short delay where things gear up for action. Contraction phase  - when the muscle is flexing its power, generating tension. Relaxation phase  - where the muscle chills out and goes back to its normal state.

Now, imagine if all our motor units fired at once. We'd be moving like robots, all jerky and awkward. Instead, they  fire asynchro...

"Does pushing workouts make you stronger at pulling workouts?" Hi Richie, Yes, they do. In fact they compliment each other. Pushing workouts may work the same muscles as pulling workouts, but their muscle mechanics are slightly different. Pushing is about compression, while pulling is about tension. But they do help each other. They are more like two sides of the same coin. So, when we do pushing workouts, we are strengthening our muscles in a way that is complementary to how pulling workouts strengthen them. This means that when we do pulling workouts, we can lift more weight and perform them with better form. To understand this better, let's think of it like this: When we push something, we are using our muscles to shorten them. This is called  concentric contraction . When we pull something, we are using our muscles to lengthen them. This is called  eccentric contraction . For example, bicep curls has both concentric and eccentric contractions: Concentric and eccentric...

Hi Kenny, On your question: “Is it better to do 3 workouts of 1 set each or 1 workout of 3 sets each?”, it depends on your fitness goals. Can I assume your goal is to train your strength and tone your muscles? If it is, then you should go for  3 SETS of 8–12REPS  for  EACH WORKOUT . The same is true for building muscle. If you want to build strong and toned muscles, you need to do multiple sets of reps. Here's some depth: When you do a set of reps, you're breaking down your muscle fibers. This breakdown process is called  MUSCLE HYPERTROPHY . After your workout, your body repairs and rebuilds the muscle fibers, making them stronger and bigger. If you only do one set of reps, your body  doesn't have enough time  to break down the muscle fibers enough to cause significant muscle growth. However, if you do three sets of reps, your body has  more time  to break down the muscle fibers and cause more muscle growth. And if you're going for  ENDURANC...

"How do myoblasts and myotubes contribute to muscle growth and regeneration?" Yo, fitness enthusiasts!  🏋️‍♂️ Gather 'round because we're diving deep into the muscle magic with  MYOBLASTS  and  MYOTUBES ! These are like the Avengers of muscle growth and regeneration, working behind the scenes to make your gains epic! 💪 Myoblasts, the Muscle Protectors: Okay, peeps, listen up! MYOBLASTS  are the unsung heroes in your muscle origin story. They're like the cool kids in school, but instead of popping gum, they pop out of  mesodermal progenitor cells  during embryo development! 🌟 They're the muscle's early squad, helping out during the growth phase by multiplying and providing nuclei for the muscle fibers. Think of them as the construction workers laying the foundation for your muscle skyscrapers! 💼 But wait, there's more—when there's an injury or some heavy lifting going on, these myoblasts activate and transform into muscle-building warriors! Myot...
