I haven't done a chin-up since way back (60 pounds ago- My record was then 27).
This was "now" MUCH to difficult, for me...!?
Then I talked to a fitness instructor, about my problem...?-
He suggested that I turn regular chin-ups into a "much easier/better" isometric exercise!-
Grab the bar (palms facing, for starters), and hop up (get a stool...), until chin is about even with the bar (you can support a little weight with legs on stool, if too difficult...).
Then just hold that postion for a few seconds... (increase time..., as is comfortable...), then let yourself slowly down.
Do this every "other" day (don't do/Arthritis...!- if joints or muscles, are sore...!).
I'm now up to four sets of 30 seconds bi-daily, and rotate palms facing or palms away (pull-up)-
My arms & back... have toned up, and I do so "!MUCH!" better at tennis/golf!
I can now do a regular chin-up, but the "extra" strain REALLY makes my joints (shoulder, elbow) ache!
I'll just stick with the isometrics...!
Notes:
1. I hung it in the bathroom doorway, to help remind me...!
2. Yes- the bar rotates a little, if not gripped firmly (this is REALLY good, for toning your wrists...!)!
3. I Love the cushioned foam grips, that don't cut off circulation to hands- like my old cushionless bar did!
