Resisted Towel Curl
Roll up a towel into a tight “snake” and grab the middle of it with both hands. Have your partner get on his knees and grab the ends. Perform curls while he resists. Record both your times.
Front Plate Raise (Not Shown)
Hold a weight plate at arm’s length as you did in the squat with plate raise. This time, do not squat. Just raise the plate straight up to eye level. Record your reps and then your partner’s.
