I've been having wrist tendinitis for months since I was back squatting wrong. Since I stopped back squatting the pain is less but still there. Is it okay to do wrist curls while having wrist tendinitis? I'm already doing hammer curls, but I lack forearm development.
All you will do is continue to delay healing, and you won't see significant forearm growth anyhow as you won't be working them heavy anyhow.
What do you do for back work?
Set 1 - Back and Bis
EZ Bar curls (wide grip easier on forearms might alternate with narrow grip with less weight)
Set 2 - Chest and Tris
Inclined DB press
Inclined DB flyes
Db Lying Triceps Extension
close grip bench
Set 3 - Legs
Stiff leg deadlift
Set 4 - Shoulders
Db Shoulder Press
rear delt flys
I think i'd just stick with that, or maybe try the farmers walk. Realistically, you will get some forearm growth from the deadlifts and rows, so straining your wrists more to try and get growth really will be counterproductive. Let it heal, then if you want to add some do it then. Personally i've never done any wrist or direct forearm work, mine aren't huge (11.5-12inch) but look good and are proportional with bicep growth
From the point where you stop doing things to irritate it, its at least 2 weeks, and even as long as 6 for it to heal, especially if you aren't using anti-inflammatories.
Maybe try alleve the naproxem sodium? But it definitely takes some time, for me last time it was around 3 weeks with high doses of anti-inflammatories.
