No matter what workout I am doing, I always keep my core muscles flexed. While doing push ups, I keep my hips slightly elevated and my core tightened. While doing pull ups, I keep my legs at a 90 degree angle. My core is always getting a secondary workout.
Abs are a fairly easy muscle to work out. Many athletes forget about obliques and lower back. While keeping my core flexed, I hold 15 pound weights at eye level and rock side to side. My legs stay straight and stationary as I bend and flex at the oblique. I girate in as many positions as I can until I feel my obliques catch fire. Always keep your core flexed while doing this workout. Once I cannot bend anymore from side to side, I then conclude my workout with Supermans.
Boxing is a great Ab/oblique workout. While fearing a bodyshot, your abs should almost always be tightened. The force and twist used to throw a punch targets those pesky lower back and oblique muscles. When I am not training these muscles in the ring, I am training them with weights. As shown below, the flexing of my obliques as I throw the right hand.
For those looking to shed weight, I encourage boxing for all. All muscles are used while boxing. You will experience a soreness in muscles you didnโt even know you had. For many, lower back abs obliques are those forgotten about muscles. I hope I was of help ๐
