I struggle with the single leg squat due to flexibility. I cannot keep my leg straight enough to get into a deep squat position. My straight leg always hits the ground first. Is there a solution to this or stretches i should be doing first?

Hey. This is Chrys one of the trainers at Hybrid
That’s really common and it’s not a strength issue, it’s mobility and positioning. When the straight leg hits the floor first, it’s usually limited ankle dorsiflexion on the squatting leg plus tight hamstrings on the straight leg. Don’t force depth yet. Use a support like holding a doorframe or pole, or squat to a box or chair so you can control the bottom without collapsing. You can also slightly bend the “straight” leg at first or let it hover lower instead of forcing it perfectly straight.
For prep, focus on ankle mobility on the squatting side and hamstring mobility on the free leg. Slow calf stretches with the knee over the toes, ankle rocks, and gentle hamstring stretches will help. Over time, as those improve, the leg will naturally stay higher and straighter. Treat the single-leg squat as a long-term skill. Control and balance come first, depth usually comes later.
