planche holds and push ups, lever holds and pull ups, muscle up variations, iron cross, hspu variations (freestanding, to the chest, on platforms, or weighted), v-holds and raises, weighted leg raises, weighted pistols, weighted unilateral good mornings (other leg stays raised), [glute ham calf raise if available],
stair climbing
difficulty on all exercices may be increased with weighted vests (I have a 100lbs vest), and ankle weights (I have 50lbs worth of ankle weights),
And I do drop sets by gradually increasing mechanical advantage (reducing torques) and / or dropping the vest and or ankle weights.
A vibration plate really adds some fun into the mix for the unilateral leg exercises and the pressing movements.
No joint pain, no risk of disc injury, even at high intensity.
