Mixed
Low-intensity resistance training combined with vascular occlusion (blood flow restriction) produces hypertrophic gains similar to high-intensity training without occlusion.
If you cannot lift heavy weights due to injury or limitation, consider using blood flow restriction (BFR) with light weights (around 50% of your max). This method can build muscle size comparable to heavy lifting by creating metabolic stress.
GoodSupportsHIGH confidence
After 16 weeks, the group that performed low-intensity training with occlusion showed a significantly greater cross-sectional area of the elbow flexor muscles as compared to low-intensity exercise without occlusion. Moreover, the hypertrophic gains realized were similar to those experienced by the moderate- to high-intensity group.
Why this rating
Based on a specific study cited (Takarada et al.) within the review.
