I decided to take one spring off my ISG so I can do some dynamic pinch work with it. I wanted to know exactly what resistance I was pinching but This chart only shows resistances for two spring settings so I did a little math to figure out what the single spring resistances would be and thought I'd post them for anyone who might be interested. 

 

 

Spring Position Resistance

1           13
2           21
3           31
4           42
5           55
6           70
7           87
8           105
9           125
10          147
11          171
12          196

 

Just fyi here's the change in resistance between each spring position:

 

p1=13

1>2=8
2>3=10
3>4=11
4>5=13
5>6=15
6>7=17
7>8=18
8>9=20
9>10=22
10>11=24
11>12=25

 

Here's the full two spring settings list:

 

3     1     45
4     1     56
4     2     64
5     1     69
5     2     77
6     1     84
5     3     87
6     2     92
7     1     101
6     3     102
7     2     109
6     4     113
7     3     118
8     1     119
8     2     127
7     4     130
8     3     137
9     1     139
7     5     143
9     2     147
8     4     148
9     3     157
1     10    161
8     5     161
9     4     168
2     10    169
8     6     176
3     10    179
9     5     181
11    1     185
4     10    190
2     11    193
9     6     196
3     11     202
5     10     203
12    1      210
9     7      213
4     11     214
2     12     218
6     10     218
5     11     227
3     12     228
7     10     235
4     12     239
6     11     242
5     12     252
8     10     253
7     11     259
6     12     267
8     11     277
7     12     284
9     11     297
8     12     303
9     12     323

The ISG seems really awesome.  I have one, I haven't used it a whole, but plan on cycling it into my training.  How did you get one of the springs off?

Yea, I bought it just as a gripper but I'm finding it's like a little swiss army knife of grip. It was actually surprisingly easy to pop the spring off with a screwdriver just levering it off.

Hey dude thanks btw for the tip on the isg and thumb training. I used it yesterday with both springs in the first two slots and got 20 reps with both thumbs at the same time. Im gonna save a ton on imtugs with this tip!
