While Drake believes in a bright future for Bitcoin, it seems that there is another approach to this, compared
with Twitter CEO Jack
Dorsi eat, who said that Bitcoin will be the only «common currency» of the Internet.
Afterwards, there was a period of rest and they did two more sets
with instructions to concentrate on their latissimus
dorsi while de-emphasizing their biceps.
As a multi-joint exercise that involves movement at the elbows, scapula and shoulders, the pull - down effectively trains a variety of muscles in the upper body,
with the latissimus
dorsi being the prime mover.
This push up made famous by American fitness expert Jack Lalanne in the 1950s is a great shoulder, latissimus
dorsi and core exercise that looks very impressive but should not take anyone
with good overall strength long to master.
To add variety to your middle back workout routine, replace the supported T - bar rows
with a different exercise that works the same muscles (latissimus
dorsi).
This exercise is all about upper body strength,
with the main area being worked out latissimus
dorsi muscle of the back.
They found that EMG amplitude increased
with increasing load in the deltoid only in the second pull, turnover, and recovery phases; in the biceps in the transition, second pull, turnover, and recovery phases; in the triceps only in the recovery phase, in the latissimus
dorsi only in the first phase, and not at all in the pectoralis major.
To do the standard version which mainly works the latissimus
dorsi (side back muscles) hang from a bar
with your arms fully extended, hands in an overhand grip and shoulder width apart, and your feet off the ground.
The Latissimus
Dorsi muscles are located on the sides of the back, Erector Spinae helps mainly
with the lower back but also works down to the buttocks and neck.
The exercise mostly targets the latissimus
dorsi muscle of the back along
with other assisting muscles like the biceps.
Many large and small muscles have relationships
with the ligaments of the sacroiliac joint including the piriformis (see «piriformis syndrome», a condition often related
with sacroiliac joint dysfunction), biceps femoris, gluteus maximus and minimus, erector spinae, latissimus
dorsi, thoracolumbar fascia, and iliacus.
It's imperative
with this movement that you protect the lower back and learn to isolate the latissimus
dorsi.
Norwood et al. (2007) explored the effect of increasing instability on latissimus
dorsi by measuring muscle activity during the bench press performed on a (1) stable bench, (2)
with the feet placed on a BOSU ball, (3) Swiss ball, or (4) Swiss ball
with feet placed on a BOSU ball.
They reported that the bench press performed
with a wide grip and a decline bench angle produced significantly greater latissimus
dorsi muscle activity than the horizontal and incline variations performed
with narrow and wide hand spacing.
In contrast, the pectoralis major overall has a small extension moment arm length, making it a weak contributor to movement in the opposite direction, along
with the latissimus
dorsi.
They reported that
with increasing instability, there was greater latissimus
dorsi muscle activity (8.5 ± 5.1 to 26.1 ± 25.2 mV).
The latissimus
dorsi is a primary shoulder extensor in the sagittal plane and displays its largest moment arm lengths
with the arm below horizontal.
When comparing the inverted row
with the barbell bent over row, they reported superior latissimus
dorsi muscle activity when performing the inverted row.
Therefore, it appears that the latissimus
dorsi is a prime mover during shoulder adduction in the frontal plane, in combination
with the teres major (Ackland et al. 2008).
They reported that latissimus
dorsi muscle activity was greater when performing the wide grip lat pull - down to the front compared
with the lat pull - down to the rear.
Therefore, the data appears to indicate the latissimus
dorsi displays at least moderately a greater proportion of type II muscle fibers and therefore may respond better to training
with heavy loads and faster speeds.
Similarly, latissimus
dorsi, posterior deltoid, biceps brachii, upper trapezius, and lower trapezius EMG amplitudes are greater in a pressing exercise performed
with a cable machine compared to
with a fixed bar path machine (Cacchio et al. 2008).
The data indicates that the latissimus
dorsi muscle is highly active during shoulder extension
with the arm near the side of the body.
Bergquist et al. (2015) compared latissimus
dorsi muscle activity when performing the lat pull - down
with a traditional cable system or elastic resistance
with a load that equalled the 10RM.
This research indicates that the latissimus
dorsi displays superior muscle activity during the pull - up compared
with the kipping pull - up.
They reported that latissimus
dorsi muscle activity was greater during the pronated lat pull - down compared
with the supinated pull - down.
Comparing deadlifts
with different grips, Beggs et al. (2011) compared the conventional deadlift performed
with a double overhand (pronated) or mixed (one hand pronated, one hand supinated) grip on latissimus
dorsi muscle activity during sets
with 60 and 80 % of 1RM load.
They report that the pronated grip pull up produced comparable (120 % vs. 117 % of maximum voluntary isometric contraction (MVIC) levels) latissimus
dorsi muscle activity compared
with the supinated chin - up exercise.
Comparing the effect of technique, Lehman et al. (2004) compared the latissimus
dorsi muscle activity during the cable - pulley seated row performed
with and without full retraction of the scapula at the peak contraction region.
Bergquist et al. (2015) compared latissimus
dorsi muscle activity when performing the single arm row
with a traditional cable system or elastic resistance
with a load that equalled the 10RM.
For the IT band and the latissimus
dorsi, the participants laid on their side
with their forearm and their feet holding their body weight.
They reported that the lat pull - down performed
with 80 % of 1RM load displayed similar latissmus
dorsi muscle activity between all three conditions.
Therefore collectively, the data appears to indicate that during pull - ups performed
with comparable loads, changes in stability and forearm motion do not affect latissimus
dorsi muscle activity.
They reported that the inverted row performed
with a supinated grip produced superior (94 % vs. 79 % of maximum voluntary isometric contraction (MVIC) levels) latissimus
dorsi muscle activity compared to the pronated grip inverted row variation.
More recent investigations have found that the latissimus
dorsi is connected
with the gluteus maximus of the opposite hip via the thoracolumbar fascia (Bogduk et al. 1998; Carvalhais et al. 2013).
Overall, therefore, the research appears to indicate that performing the lat pull - down
with a pronated grip produces greater latissimus
dorsi activity than narrow, supinated and neutral grip conditions.
Comparing different types of rowing movements, Fenwick et al. (2009) compared exercises
with varying degrees of spine loading on the latissimus
dorsi muscle activity.
Lusk et al. (2010) compared the lat pull - down performed
with a pronated and supinated hand - grip on latissimus
dorsi muscle activity.
This may imply that exercises
with peak contractions at just below the horizontal are most helpful for targeting the latissimus
dorsi during this joint action.
