The old style T – Bar was and still is one of the best exercises one can do to develop overall body strength. It should be given the same credit as the squat and deadlift as it definitely uses much of the body’s musculature when doing the lift. Upper back, traps, spinal erectors, abs, hamstings, glutes are the main muscles used… Biceps, forearms, grip, quads and even calves are used.
When doing this lift you should not be bent at 90 degrees as is generally suggested for rowing moves. You should be more upright almost inline with the bar as it moves upward as the resistance is changed due to the set up as compared to a regular bar bell row exercise.
