A couple TRI Exercises....
Triceps Extension with Band
Lie on a step and loop a resistance band underneath the end where your head is.
Hold an end of the band in each hand on either side of your forehead, palms facing in, elbows bent. Straighten arms, bringing knuckles toward ceiling.
Return to start and repeat X times. (However many reps)Can also use DB's or BB of course.
Triceps Push-Up
Lie on left side with legs together, slightly bent. Place left hand on right hip and right hand on floor in front of left shoulder.
Extend right arm, lifting left shoulder off floor. Bend elbow to lower, without touching shoulder to floor.
Repeat X times.
Have you tried separating your legs further apart for side planks? This will help with balance. Good Luck!
