Does arm position change muscle growth with light weights and blood flow restriction?
Similar Regional Hypertrophy of the Elbow Flexor Muscles in Response to Low-Load Training With Vascular Occlusion at Short Versus Long Muscle Lengths

Surprising Findings
Shoulder position (long vs. short muscle length) had no effect on hypertrophy during BFR training.
Most research suggests training at long muscle lengths increases growth due to higher mechanical tension. This contradicts that idea under BFR conditions.
Practical Takeaways
Use blood flow restriction with light weights (30% 1RM) for arm training if you're injured, traveling, or want joint-friendly growth.

For guys who lift weights, doing arm curls with the arm stretched out doesn’t build more muscle than doing them with the arm bent, even when using light weights and blood flow restriction — at least over 3 weeks.
Doing light weightlifting with blood flow restriction four times a week for three weeks can make arm muscles grow a little in young, trained guys — about 4% to 8% bigger.
When people do light weight training with blood flow restriction on their biceps, the muscle grows evenly no matter if they do the exercise with their arm bent a lot or a little — growth looks the same along the whole muscle.
Doing light weight training with restricted blood flow can still make your arm muscles grow bigger — and it doesn’t cause swelling or damage, according to a 3-week study on people’s biceps.
For young guys who lift weights, squeezing the biceps at the top or bottom of the move doesn’t make a difference in muscle growth when using light weights with blood flow restriction.
