A agree with everything others have posted. My shoe recommendation was due to in tennis shows, the squishy soles and ankle instability makes it hard to keep your feet in one position without a sliding motion. I think youll notice a HUGE difference. Even sum steel toed boots.
Also, like above...Steps are critical.. Once you get better at it, 2 steps buddy and go. Ive seen so many lifters waste valuable air and energy trying to get their feet planet. Brad Gillingham told me once. Step/Step/Squat.
Keep up the good work.
