- Start with isometric loading (initially for analgesics) and progress to isotonic loading (heavy and slow resistance)
Why do we need to stay below 60 degrees of knee flexion with decline squatting?
To avoid excessive patellofemoral load. When under 60, you are loading the patellar tendon more.

How is a heel fat pad issue different from plantar heel pain?
Changes in the viscoelastic properties of the heel fat pad, in which it reduces its ability to dissipate the compressive forces applied during gait.
