At this age (well, at every age) it is imperative to get enough rest between exercise days. The heart rate variability (HRV, there are apps for that) is a good indicator.
For muscle growth I can from personal experience highly recommend Glycine (available from vegan sources). It can be used as sweetener while helping keep blood glucose down. One study found it can boost muscle growth 400% in young pigs.
Glycine study performed on young pigs: https://academic.oup.com/jn/article/144/10/1540/4575112 https://academic.oup.com/jn/article/144/10/1540/4575112
Here’s one on mouse muscle cells: https://academic.oup.com/jn/article/146/12/2461/4589973 https://academic.oup.com/jn/article/146/12/2461/4589973
- radicaldreamer 5y agoWhat is a reputable/lab tested source for glycine? I assume that ordering random tablets from Amazon isn’t the best way to do it.
- manmal 5y agoI’ve been buying from a reputable German company, they provide lab test results on request. It ships as powder, in a 500g bag
- travoc 5y agoNever put anything from Amazon into your body. Their sourcing policies and procedures put all the risk of counterfeits onto the customer.
- billh 5y agoA few years ago I bought some shampoo from Amazon that was very clearly counterfeit. The product and packaging was so bad that if anyone was paying attention to the supply line they should have been able to figure it out. Since then my general rule has been "If it goes on me or in me, I'm not getting it from Amazon"
- bserge 5y agoKey word being "Amazon". Order from a reputable seller from their own store.

I've heard it said that there is no such thing as over-training only "under resting". > The heart rate variability (HRV, there are apps for that) is a good indicator. Can you give more details on this? How does it work, what number(s) to look at, etc.

- CJefferson 5y agoWhat study? Weightlifting is full of claims of miracle supliments, and usually the best claim much lower improvements than that.

- beaconstudios 5y agoExamine.com is a good source for supplement info because they correlate multiple studies into a meta analysis: https://examine.com/supplements/glycine/ https://examine.com/supplements/glycine/
- ac29 5y ago> One study found it can boost muscle growth 400% in young pigs. The study doesnt say that. It says protein synthesis in vitro (in a test tube) using cultured pig intestinal cells increased by 36-419%. This doesn't necessarily mean anything at all for increasing muscle mass.

- manmal 5y agoTrue, thanks for the correction. I think I got the notion about muscle growth from a news article that reported on this paper.
