How to choose
Choose a movement whose range and load can progress, then keep the pelvis and trunk action aligned with the intended exercise.
Keep the chosen movement stable long enough to compare performance, unless pain, equipment or programme fit requires a change.
Catalogue quality
Bulk Coach's exercise catalogue contains names, instructions, muscles, equipment, movement patterns and substitutions. Individual exercise URLs remain outside the sitemap until their instructions and added programming guidance receive a recorded founder review.
