The muscular system is made up of over 600 muscles. While we won’t be covering all 600 plus individual muscles in this overview video, we will be discussing the …
– Main functions of the muscular system
– 5 major properties of the muscular system
– 5 types of muscle movements withing the muscular system
– 3 types of muscles within the muscular system
– and how all of this works together to make up the muscular system.
Now there is much more to discuss about the muscular system but that’s as far as we will go in this introductory video. After watching this video you should at least have a basic understanding of what makes up the muscular system, its properties and functions. For a more in depth study of the muscular system, look for future CTE videos where we will cover topics such as the 14 major muscle groups, as well as topics such as common diseases and conditions specific to the muscular system.
The primary purpose for the Muscular system is to provide movement for the body. The muscles receive their ability to move the body through the nervous system.
Get ready for a full-body strength-training workout with Nike Global Master Trainer Betina Gozo. This workout includes circuits to work every muscle. Grab a pair of medium weights, anywhere from 8 to 20 pounds, and get ready for a challenge with a series of exercises including tempo squats, single-leg deadlifts, and skaters. After this workout, you’ll feel strong, sculpted, and just the right amount of sore.

_________________________________________________________
⭐️FAQ’s + TRAINER TIPS:
► What if I don’t have dumbbells at home? Try subbing filled water bottles, soup cans or jugs of laundry detergent.
►Will this workout make me ‘bulky’? NO! Women getting ‘bulky’ from strength training is a fitness myth. Lifting weights will NOT make you bulky — just stronger!
► What are the benefits of STRENGTH TRAINING for women:
➕ Strength training increases metabolism.
➕ Strength training builds lean muscle (without getting bulky).
➕ Strength training effectively burns body fat to help women lose weight.
➕ Strength training reduces the risk of heart disease (the number one killer of women).
➕ Strength training enhances mood and reduces stress.
► Is this pregnancy-friendly 🤰 ? YES. I originally filmed this during my first pregnancy, and we went back and added this full-length video when I was postpartum! If you’re not comfortable on your back, take moves 6 and 7 from a medicine ball.
►How many days a week should you do strength training?
Aim three days a week of strength training. Include full-body workouts, like this strength training routine for women, that focus on compound exercises.

Finally: a workout suitable for BEGINNERS. // Werbung
What makes this “beginner friendly”?
1. I used BASIC movements, that are not too complicated or hard to perform
2. the workout sequences REPEAT, giving you a chance to get used to the movements & get a better feeling for them
3. a couple of BREAKS. Haha I know you wanted them! The workout sequences are only between 2 or 4 minutes long. Then it’s time to catch a breath!
4. includes warm up exercises
5. includes a cool down sequence in the end
But let’s make this clear: I was still feeling a serious burn in my muscles and I was still sweating ♥︎
This video is super effective and especially the SLOWNESS gives you so much room to perform everything concentrated, thinking of the exact muscles you want to train. The burn was seriously insane for me!
No Equipment necessary and not much space needed 🙂
The video is in full length which means you can just follow whatever I’m doing 30s for each exercise.
I recommend switching up your workouts to give your muscles enough time to recover and to hit them from different angles. If you want to challenge your muscles more: check out my Sixpack Video, 20min Booty Workout, Sexy Arm Trainings or the Calorie Burn Session! Those ones are quicker & harder. But try your best!

Each time you take a step, 200 muscles work in unison to lift your foot, propel it forward, and set it down. It’s just one of the many thousands of tasks performed by the muscular system: this network of over 650 muscles covers the body and is the reason we can blink, smile, run, jump, and stand upright. So how does it work? Emma Bryce takes you into the body to find out.

We’re kicking off our exploration of muscles with a look at the complex and important relationship between actin and myosin. Your smooth, cardiac, and skeletal muscles create movement by contracting and releasing in a process called the sliding filament model. Your skeletal muscles are constructed like a rope made of bundles of protein fibers, and that the smallest strands are your actin and myosin myofilaments. Its their use of calcium and ATP that causes the binding and unbinding that makes sarcomeres contract and relax.
