2/ The maximum neuromuscular engagement for inclined leg press is achieved at 90°, 60°-70° for squats.

3/ Slower, controlled movements give the best results, as they lead to increased muscle protein synthesis rates compared to faster movements

0/ Here is the standardized data by age.

Weight pushed per bodyweight = 1RM leg press/ bodyweight
