Does lazy Iron’s research for him
“When blood glucose drops (during exercise or with carbohydrate restriction), insulin levels generally drop as well.”
“When blood glucose increases, insulin levels increase as well, causing glucose in the bloodstream to be stored as glycogen in the muscle or liver… Protein synthesis is stimulated and free amino acids (the building blocks of proteins) are be moved into muscle cells and incorporated into larger proteins.”
“Glucagon is essentially insulin’s mirror hormone and has essentially opposite effects. Like insulin, glucagon(s) … primary role is also to maintain blood glucose levels. However, glucogon acts by raising blood glucose when it drops below normal.”
“Glucagon’s main action is in the liver, stimulating the breakdown of liver glycogen which is then released into the bloodstream.”
“Under normal conditions, glucagon has very little effect in tissues other than the liver (i.e. fat and muscle cells). However, when insulin is very low, as occurs with carbohydrate restriction and exercise, glucagon plays a minor role in muscle glycogen breakdown …”
“From the above descriptions, it should be clear that insulin and glucagon play antagonistic roles to one another. Whereas insulin is primarily a storage hormone, increase storage of glucose, protein and fat in the body; glucagon’s primary role is to mobilize those same fuel stores for use by the body.”
“As a general rule, when insulin is high, glucagon levels are low.”
“… insulin and glucagon play the major roles in determining the anabolic or catabolic state of the body.”
“When blood glucose increases … insulin is released to lower blood glucose back to normal. The greatest increase in blood glucose levels (and the greatest increase in insulin) occurs from the consumption of dietary carbohydrates.”
“Growth hormone (GH) is another peptide hormone which has numerous effects on the body, both on tissue growth as well as fuel mobilization. GH is released in response to a variety of stressors the most important of which for our purposes are exercise, a decrease in blood glucose … As its name suggests, GH is a growth promoting hormone, increasing protein synthesis in the muscle and liver. GH also tends to mobilize FFA from fat cells for energy.”
“High GH levels along with high insulin levels (as would be seen with a protein and carbohydrate containing meal) will raise IGF-1 (insulin like growth factor-1) levels as well as increasing anabolic reactions in the body.” [1]
Cliff notes for Iron: exercise causes blood glucose to drop -> insulin drops -> glucagon increases -> GH increases. Glucagon is catabolic, insulin anabolic. GH with glucagon won’t help much. GH with insulin will help much. Follow up weights program with protein and carbohydrate meal/shake soon after.

But at any rate, I would bet that when you get into it after a few workouts, doing 140 x 20 will be easier than when you did 100 x 20 (hopefully).
