How To Do Sumo Deadlift

sumo deadlift

I read a Frederic Delavier’s book « Strength Training Anatomy » and I learned good stuff.

Standing with the barbell on the floor in front of you. Your legs spread with your feet outside (always in your knees axis) :

  • Bent your legs to have your thighs in horizontal. Your arms are straight, you take the barbell with a pronated grip. Your hands on the barbell are to your shoulders’ width. You have the possibility to have one hand with a supinated grip and the other with a pronated grip to prevent the barbell from rolling. And with this technique, you can lift an extremely heavy weight.

  • Inhale and block your breath. Arch slightly your back, squeeze your abs and you stretch your legs by straightening your torso to have a vertical position with your shoulder drawn back. Exhale at the end of the movement.

  • Put back the barbell on the floor by blocking your breath.

It’s important to keep your back straight during all the movement to avoid injury.

This exercise works especially quadriceps muscles and adductor muscles.

This exercise works less the back’s muscles than the classic deadlift because the back is less bent at the starting position.

Note

It’s important to lift the barbell in front of your shins at the beginning of the movement.

Do this exercise with light weights and high sets (maximum 10 sets) to strengthen the lumbar’s region by working thighs and gluteus.

If you do this exercise with heavy weight, you need to be careful to not trauma hips joints, adductors muscles, and lumbosacral junction.

The sumo deadlift is one of the 3 powerlifting’s movements.

Stretching For Squat

stretching squat

I read a Frederic Delavier’s book « Strength Training Anatomy » and I learned good stuff.

Here is a stretching exercice often done by the powerlifters to avoid having muscle tears during the squat. It’s a stretching exercise to do during the warm-up session and between the first sets.

This stretching exercise involves crouching slowly while hanging on a stable support such as a pole or the frame of a machine to flex your thighs.

This movement corresponds to squat flexion and this allows you to stretch adductors, mainly adductor magnus. The adductors magnus is the muscle the most frequently injured due to the excessive tilt of the torso with heavy weight.

This exercice stretches quadriceps (except rectus femoris), gluteus maximus and the set of small, deep, external rotator muscles of the hip that stabilize and slow down the anterior tilt of the pelvis during crouching.

Note

To better feel the stretch of the leg you can move the weight of your body on the right leg and then on the left leg.

This exercise works the upper part of the trapezius and levator scapulae.

This machine is excellent to do set with high reps.

It’s funny because the clavicles and the shoulder blades are hung by the trapezius like the deck of a bridge suspended by metal cables.

Explanation Of The Challenge And Data

challenge

I have just enrolled in a Data Science course on Udemy  and I learned good stuff.

This is the 1st challenge. Use your web browser to go to superdatascience website  to download a data set. In the « Part 1 Visualization » section, click on « Offices Supplies » to download the file « OfficeSupplies.csv ».

data csv file

To organize myself, I created a folder « Visualization » with 3 subfolders. Each subfolder corresponds to the section of « Visualization ». I put the data set « OfficeSupplies.csv » in the 1st subfolder.

data csv file

« OfficeSuplies.csv » is a CSV file. A CSV file is a text file that represents an table but the elements separated by comma.

You can open this CSV file with NotePad++  for PC or with Sublime Text  for Mac.

On the 1st line (column title), we see that we have 6 columns. Each column separated by a comma and the file contains 44 lines.

data csv file

You can also open a CSV file with Excel, OpenOffice  or LibreOffice  to have a table, which is easier to read.

To open a CSV file with Excel, here are the instructions :

  • Open a blank workbook

  • Go to Data tab

  • Click button « From Text » in the general external data section

  • Select your CSV file

  • Follow the Text Import Wizard (in step 2, select the delimiter of your text).

data csv file

This data set contains data from a store that sells office equipment :

  • Order date – date of sale

  • Region – The store is in 3 region (East, Central and West)

  • Rep – salesperson’s first name

  • Item – product’s name

  • Units – product’s quantity

  • Unit Price – price per unit

Each line shows how many sales there were for a product.

The challenge is to help the manager to know who made the most sales per region in the period of this data set. The period of this data set is from July 2014 to June 2015.

The person who made the most sales in each region has a bonus and there are 3 bonus so 1 bonus per region.

It’s will this challenge that we’ll use Tableau Public.

How To Do Barbell Shrugs

barbell shrugs

I read a Frederic Delavier’s book « Strength Training Anatomy » and I learned good stuff.

Stand with your legs slightly apart. You’re in front of the barbell which is on the floor or on a support :

  • Take the barbell with a pronated grip or a over-under grip if the weight is heavy. The spacing of your hands is your shoulder’s width.

  • Your arms are relaxed with you back straight and your abs squeezed. Shrug your shoulders.

This exercise works the upper trapezius and a little bit deltoids.

Note

When you lift heavy with a over-under grip, it’s advisable to change the hand grip to each set to balance the trapezius. Do a set with the right hand with a pronated grip and the left hand with a supinated grip and the next set the right hand with a supinated grip and the left hand with a pronated grip.

Bench Press And Elbow Pain

elbow pain

I read a Frederic Delavier’s book « Strength Training Anatomy » and I learned good stuff.

Elbows pain arrives because of bench press. This pathology of wear is linked to excessive training of long sets.

At the end of the bench press movement, when you lock your arm to block the barbell, it causes rubbing and micro-trauma on your joints. And this can create inflammation.

Note : This pathology which caused only by bench press can, rarely, create intra-articular calcifications. In this case, surgical operation is often the only solution to recover the complete arm’s extension.

If you feel pain at elbows, it’s advisable to stop for several days the exercies of arms extension to avoid complications. When you restart your workout, do bench press without locking your arms at the end of the movement until the pain has completely disappeared.
